+# AI Coding Guidelines for TheChart Project
+
+## Project Overview
+- **Project Name:** TheChart (Medication Tracker)
+- **Purpose:** Desktop application for tracking medications and pathologies.
+- **Tech Stack:** Python 3.x, Tkinter, Pandas, modular architecture.
+- **Key Features:**
+  - Add/edit/delete daily medication and pathology entries
+  - Visual graphs and charts
+  - Data export
+  - Keyboard shortcuts
+  - Theming support
+
+## Coding Guidelines
+
+### 1. Code Style
+- Follow PEP8 for Python code (indentation, naming, spacing).
+- Use type hints for all function signatures and variables where possible.
+- Use docstrings for all public methods and classes.
+- Prefer f-strings for string formatting.
+- Use snake_case for variables/functions, CamelCase for classes.
+- Keep lines under 88 characters.
+- Use descriptive names for variables and functions to enhance readability.
+- Avoid global variables; use class attributes or method parameters instead.
+- Use logging for debug/info messages instead of print statements.
+- Use .venv/bin/activate.fish as the virtual environment activation script.
+- The package manager is uv.
+- Use ruff for linting and formatting.
+- The terminal uses fish shell.
+
+### 2. Architecture & Structure
+- Maintain separation of concerns: UI, data management, and business logic in their respective modules.
+- Use manager classes (e.g., DataManager, UIManager, ThemeManager) for encapsulating related functionality.
+- UI elements and data columns must be generated dynamically based on current medicines/pathologies.
+- New medicines/pathologies should not require changes to main logic—use dynamic lists and keys.
+- Avoid hardcoding values; use configuration files or constants.
+- Adopt a modular project structure following python best practices.
+
+### 3. Error Handling
+- Use try/except for operations that may fail (file I/O, data parsing).
+- Show user-friendly error messages via messagebox dialogs.
+- Log errors and important actions using the logger.
+
+### 4. User Experience
+- Always update the status bar and provide feedback for user actions.
+- Use confirmation dialogs for destructive actions (e.g., deleting entries).
+- Support keyboard shortcuts for all major actions.
+- Keep the UI responsive and avoid blocking operations in the main thread.
+
+### 5. Data Handling
+- Use Pandas DataFrames for all data manipulation.
+- Always check for duplicate dates before adding new entries.
+- Store medicine doses as a string (e.g., "time:dose|time:dose") for each medicine.
+- Support dynamic addition/removal of medicines and pathologies.
+
+### 6. Testing & Robustness
+- Validate all user input before saving.
+- Ensure all UI elements are updated after data changes.
+- Use batch operations for updating UI elements (e.g., clearing and repopulating the table).
+
+### 7. Documentation
+- Keep code well-commented and maintain clear docstrings.
+- Document any non-obvious logic, especially dynamic UI/data handling.
+
+### 8. Performance
+- Use efficient methods for updating UI elements (e.g., batch delete/insert for Treeview).
+- Avoid unnecessary data reloads or UI refreshes.
+- Use multi-threading when appropriate.
+
+## When Generating or Reviewing Code
+- Respect the modular structure—add new logic to the appropriate manager or window class.
+- Do not hardcode medicine/pathology names—always use dynamic keys from the managers.
+- Preserve user feedback (status bar, dialogs) for all actions.
+- Maintain keyboard shortcut support for new features.
+- Code Refactoring is allowed as long as it does not change the external behavior of the code.
+- Ensure compatibility with the existing UI and data model.
+- Write clear, concise, and maintainable code with proper type hints and docstrings.
+- Avoid using deprecated imports or patterns.
+- Remove any warnings or deprecation notices from the codebase.
+- Replace legacy code.
+
+---
+
+**Summary:**
+This project is a modular, extensible Tkinter application for tracking medication and pathology data. Code should be clean, dynamic, user-friendly, and robust, following PEP8 and the architectural patterns already established. All new features or changes should integrate seamlessly with the existing managers and UI paradigms, unless instructed otherwise.
+
+
+**Notes:**
+A robust Python project directory structure is crucial for maintainability, scalability, and collaboration. Key best practices include:
+
+    Root Project Directory:
+        Create a top-level directory for your project, typically named after the project itself.
+    Source Code (src/ or my_package/):
+        Modern approach: Place all application source code within a src/ directory. This clearly separates source code from other project files.
+        Alternative: If your project is a single package, the main package directory (e.g., my_package/) can reside directly under the root, containing your modules and __init__.py.
+        Modularity: Break down your code into smaller, logical modules within this directory, each with a clear responsibility.
+        __init__.py: Include an __init__.py file in every directory intended to be a Python package, marking it as importable.
+    Tests (tests/):
+        Create a dedicated tests/ directory at the root level to house all your test files.
+        Structure tests to mirror the application's module structure for easier navigation and understanding.
+    Documentation (docs/):
+        Include a docs/ directory for project documentation, including usage guides, API references, and design documents.
+    Configuration (config/ or pyproject.toml):
+        Use pyproject.toml for modern project configuration, including project metadata, dependencies, and tool configurations (linters, formatters, test runners).
+        For application-specific or environment-dependent configurations, consider a config/ directory or environment variables.
+    Entry Point (main.py or cli.py):
+        Designate a clear entry point for your application, often main.py or cli.py for command-line interfaces. This file should primarily orchestrate the application's flow and delegate logic to other modules.
+    Other Important Files:
+        README.md: A comprehensive README at the root level providing project overview, installation instructions, and usage examples.
+        LICENSE: A license file specifying the terms of use and distribution.
+        .gitignore: For version control, specifying files and directories to be ignored by Git (e.g., virtual environments, compiled files, sensitive data).
+        requirements.txt: (or managed via pyproject.toml): Lists project dependencies.
+    Virtual Environments:
+        Utilize virtual environments (e.g., venv, conda) to isolate project dependencies and avoid conflicts. The virtual environment directory (e.g., .venv/) should be ignored by version control.

+
+
+
+### Overview
+
+TheChart application now supports full menu theming that integrates seamlessly with the application's theme system. All menus (File, Tools, Theme, Help) will automatically adopt colors that match the selected application theme.
+
+### Features
+
+#### Automatic Theme Integration
+- Menus automatically inherit colors from the current application theme
+- Background colors are slightly adjusted to provide subtle visual distinction
+- Hover effects use the theme's accent colors for consistency
+
+#### Supported Menu Elements
+- Main menu bar
+- All dropdown menus (File, Tools, Theme, Help)
+- Menu items and separators
+- Hover/active states
+- Disabled menu items
+
+#### Theme Colors Applied
+
+For each theme, the following color properties are applied to menus:
+
+- **Background**: Slightly darker/lighter than the main theme background
+- **Foreground**: Uses the theme's text color
+- **Active Background**: Uses the theme's selection/accent color
+- **Active Foreground**: Uses the theme's selection text color
+- **Disabled Foreground**: Grayed out color for disabled items
+
+### Technical Implementation
+
+#### ThemeManager Methods
+
+##### `get_menu_colors() -> dict[str, str]`
+Returns a dictionary of colors specifically optimized for menu theming:
+```python
+{
+    "bg": "#edeeef",           # Menu background
+    "fg": "#5c616c",           # Menu text
+    "active_bg": "#0078d4",    # Hover background
+    "active_fg": "#ffffff",    # Hover text
+    "disabled_fg": "#888888"   # Disabled text
+}
+```
+
+##### `configure_menu(menu: tk.Menu) -> None`
+Applies theme colors to a specific menu widget:
+```python
+theme_manager.configure_menu(menubar)
+theme_manager.configure_menu(file_menu)
+```
+
+#### Automatic Updates
+
+When themes are changed using the Theme menu:
+1. The new theme is applied to all UI components
+2. The menu setup is refreshed (`_setup_menu()` is called)
+3. All menus are automatically re-themed with the new colors
+
+### Usage Example
+
+```python
+## Create menu
+menubar = tk.Menu(root)
+file_menu = tk.Menu(menubar, tearoff=0)
+
+## Apply theming
+theme_manager.configure_menu(menubar)
+theme_manager.configure_menu(file_menu)
+
+## Menus will now match the current theme
+```
+
+### Color Calculation
+
+The menu background color is automatically calculated based on the main theme:
+
+- **Light themes**: Menu background is made slightly darker than the main background
+- **Dark themes**: Menu background is made slightly lighter than the main background
+
+This provides subtle visual distinction while maintaining theme consistency.
+
+### Supported Themes
+
+Menu theming works with all available themes:
+- arc
+- equilux
+- adapta
+- yaru
+- ubuntu
+- plastik
+- breeze
+- elegance
+
+### Testing
+
+A test script is available to verify menu theming functionality:
+
+```bash
+cd /home/will/Code/thechart
+.venv/bin/python scripts/test_menu_theming.py
+```
+
+This script creates a test window with menus that can be used to verify theming across different themes.

+# Migration Guide: Canonical Imports and Running TheChart
+
+This project now uses the canonical package `thechart.*` for all imports.
+
+What changed
+- Legacy shim modules under `src/` (e.g., `src/ui_manager.py`) remain only for compatibility and now emit `DeprecationWarning`.
+- Canonical modules live under `src/thechart/` and should be imported directly.
+
+Do this
+- Imports:
+  - from thechart.ui import UIManager, ThemeManager
+  - from thechart.analytics import GraphManager
+  - from thechart.data import DataManager
+  - from thechart.export import ExportManager
+  - from thechart.managers import MedicineManager, PathologyManager
+  - from thechart.search.search_filter import DataFilter, QuickFilters, SearchHistory
+  - from thechart.core.logger import init_logger
+  - from thechart.core.constants import LOG_LEVEL, LOG_PATH, LOG_CLEAR, BACKUP_PATH
+  - from thechart.core.auto_save import AutoSaveManager, BackupManager
+  - from thechart.core.error_handler import ErrorHandler, OperationTimer, handle_exceptions
+  - from thechart.core.preferences import get_pref, set_pref, load_preferences, save_preferences, reset_preferences
+  - from thechart.core.undo_manager import UndoManager, UndoAction
+  - from thechart.validation import InputValidator
+
+- Run the app:
+  - python -m thechart
+
+Avoid this
+- from src.ui_manager import UIManager (deprecated)
+- from ui_manager import UIManager (deprecated)
+
+Notes
+- Deprecation shims will be removed once all usages are migrated.
+- Tests will be updated separately to import from `thechart.*` directly.

-```
+### Prerequisites
+- Python 3.11+
+- UV package manager (recommended) or pip
+- Virtual environment support

-#### Verify Installation
-```shell
-python3.13 --version
-uv --version
-```
-
-## Installation
-
-### Quick Setup (Recommended)
-The Makefile is configured to use the fish shell by default. For other shells, see the [shell-specific instructions](#shell-specific-activation) below.
-
-**Note:** The current Makefile still uses Poetry commands. If you've switched to uv, you may need to update the Makefile or use the manual installation method below.
-
-```shell
-make install
-```
-
-This command will:
- Set up the Python virtual environment using uv
- Install all required dependencies
- Install development dependencies
- Set up pre-commit hooks for code quality
- Run initial code formatting and linting
-
-### Manual Installation
-If you prefer to set up the environment manually:
-
-1. **Clone the repository** (if not already done):
-```shell
+### Setup
+```bash
+# Clone the repository
 git clone <repository-url>
 cd thechart
-```

-2. **Create and activate virtual environment:**
-```shell
-uv venv --python 3.13
+# Install with UV (recommended)
 uv sync
-```

-3. **Install pre-commit hooks** (for development):
-```shell
-uv run pre-commit install --install-hooks --overwrite
-uv run pre-commit autoupdate
-```
+# Or install with pip
+python -m venv .venv
+source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+pip install -r requirements.txt

-### Migrating from Poetry to uv
-
-If you have an existing Poetry setup and want to migrate to uv:
-
-1. **Remove Poetry environment** (optional):
-```shell
-poetry env remove python
-```
-
-2. **Create new uv environment:**
-```shell
-uv venv --python 3.13
-uv sync
-```
-
-3. **Update your workflow:** Replace `poetry run` with `uv run` in your commands.
-
-The `pyproject.toml` file remains compatible between Poetry and uv, so no changes are needed there.
-
-### Shell-Specific Activation
-
-If the automatic environment activation doesn't work or you're using a different shell, manually activate the environment:
-
-#### fish shell (default)
-```shell
-source .venv/bin/activate.fish
-```
-or use the convenience command:
-```shell
-make shell
-```
-
-#### bash/zsh
-```shell
-source .venv/bin/activate
-```
-
-#### PowerShell (Windows)
-```shell
-.venv\Scripts\Activate.ps1
-```
-
-#### Using uv run (recommended)
-For any command, you can use `uv run` to automatically use the virtual environment:
-```shell
-uv run python src/main.py
-uv run pre-commit run --all-files
-```
-
-## Running the Application
-
-### Quick Start
-After installation, run the application with:
-```shell

+# UI Flickering Fix Summary
+
+## Problem Description
+The UI elements were flickering when the user scrolled through the table, causing a poor user experience and making the application feel unresponsive.
+
+## Root Causes Identified
+
+1. **Auto-save triggering full UI refresh**: The `_auto_save_callback` method was calling `refresh_data_display()` every 5 minutes, which completely refreshed the UI even during user interaction.
+
+2. **Real-time filter updates**: The search filter widget was triggering `update_callback()` on every keystroke, causing immediate and frequent full data refreshes.
+
+3. **Inefficient tree updates**: The `refresh_data_display` method was loading data multiple times and completely replacing all tree items, causing visible flickering.
+
+4. **Lack of scroll position preservation**: When the tree was refreshed, the user's scroll position was lost, causing jarring jumps.
+
+## Solutions Implemented
+
+### 1. Auto-save Optimization (`thechart` main application)
+```python
+def _auto_save_callback(self) -> None:
+    """Callback function for auto-save operations."""
+    try:
+        # Only save data, don't refresh the display during auto-save
+        # This prevents flickering during user interaction
+        logger.debug("Auto-save callback executed successfully")
+    except Exception as e:
+        logger.error(f"Auto-save callback failed: {e}")
+```
+**Impact**: Eliminates UI interruptions during auto-save operations.
+
+### 2. Debounced Filter Updates (`thechart.ui.search_filter_ui`)
+- Added 300ms debouncing mechanism to prevent excessive filter updates
+- Consolidated filter updates into a single batch operation
+- Replaced immediate callbacks with debounced updates
+
+```python
+def _debounced_update(self) -> None:
+    """Update filters with debouncing to prevent excessive calls."""
+    # Cancel any pending update and schedule a new one
+    if self._update_timer:
+        with contextlib.suppress(tk.TclError):
+            self.parent.after_cancel(self._update_timer)
+
+    self._update_timer = self.parent.after(
+        self._debounce_delay, self._execute_filter_update
+    )
+```
+**Impact**: Reduces filter update frequency from every keystroke to maximum once per 300ms.
+
+### 3. Efficient Tree Updates (application update path)
+- Separated tree update logic into `_update_tree_efficiently()` method
+- Added scroll position preservation
+- Eliminated redundant data loading
+- Used `update_idletasks()` for smoother UI updates
+
+```python
+def _update_tree_efficiently(self, df: pd.DataFrame) -> None:
+    """Update tree view efficiently to reduce flickering."""
+    # Store and restore scroll position
+    current_scroll_top = 0
+    with contextlib.suppress(tk.TclError, IndexError):
+        current_scroll_top = self.tree.yview()[0]
+
+    # Batch operations and restore position
+    # ... update logic ...
+
+    self.root.update_idletasks()
+    with contextlib.suppress(tk.TclError, IndexError):
+        if current_scroll_top > 0:
+            self.tree.yview_moveto(current_scroll_top)
+```
+**Impact**: Maintains scroll position and reduces visual disruption during updates.
+
+### 4. Optimized Data Loading (application update path)
+- Eliminated redundant `load_data()` calls
+- Used single data copy for both filtered and unfiltered operations
+- Improved memory efficiency
+
+```python
+def refresh_data_display(self, apply_filters: bool = False) -> None:
+    # Load data once and make a copy for graph updates
+    df: pd.DataFrame = self.data_manager.load_data()
+    original_df = df.copy()  # Keep a copy for graph updates
+
+    # Apply filters only if needed
+    if apply_filters and self.data_filter.get_filter_summary()["has_filters"]:
+        df = self.data_filter.apply_filters(df)
+```
+**Impact**: Reduces I/O operations and memory usage.
+
+### 5. Scroll Optimization (`thechart.ui.ui_manager`)
+- Added optimized scroll command with threshold-based updates
+- Reduced scrollbar update frequency for better performance
+
+```python
+def _optimize_tree_scrolling(self, tree: ttk.Treeview) -> None:
+    """Optimize tree scrolling to reduce flickering and improve performance."""
+    last_scroll_position = [0.0, 1.0]
+
+    def optimized_yscrollcommand(first, last):
+        # Only update if position significantly changed
+        first_f, last_f = float(first), float(last)
+        if (abs(first_f - last_scroll_position[0]) > 0.001 or
+            abs(last_f - last_scroll_position[1]) > 0.001):
+            # Update scrollbar efficiently
+```
+**Impact**: Reduces scroll update frequency and improves scrolling smoothness.
+
+## Testing Results
+
+The application now runs without the previous UI flickering issues:
+- ✅ Smooth scrolling through table data
+- ✅ No interruptions from auto-save operations
+- ✅ Responsive search/filter updates with debouncing
+- ✅ Preserved scroll position during data updates
+- ✅ Reduced CPU usage during scroll operations
+
+## Files Modified
+
+1. Main application - Auto-save optimization and efficient tree updates
+2. `thechart.ui.search_filter_ui` - Debounced filter updates
+3. `thechart.ui.ui_manager` - Optimized scroll handling
+
+## Verification
+
+Run the test script to verify improvements:
+```bash
+python test_ui_flickering_fix.py
+```
+
+The application should now provide a smooth, flicker-free user experience when scrolling through data entries.

+# Menu Theming Documentation
+
+## Overview
+
+TheChart application now supports full menu theming that integrates seamlessly with the application's theme system. All menus (File, Tools, Theme, Help) will automatically adopt colors that match the selected application theme.
+
+## Features
+
+### Automatic Theme Integration
+- Menus automatically inherit colors from the current application theme
+- Background colors are slightly adjusted to provide subtle visual distinction
+- Hover effects use the theme's accent colors for consistency
+
+### Supported Menu Elements
+- Main menu bar
+- All dropdown menus (File, Tools, Theme, Help)
+- Menu items and separators
+- Hover/active states
+- Disabled menu items
+
+### Theme Colors Applied
+
+For each theme, the following color properties are applied to menus:
+
+- **Background**: Slightly darker/lighter than the main theme background
+- **Foreground**: Uses the theme's text color
+- **Active Background**: Uses the theme's selection/accent color
+- **Active Foreground**: Uses the theme's selection text color
+- **Disabled Foreground**: Grayed out color for disabled items
+
+## Technical Implementation
+
+### ThemeManager Methods
+
+#### `get_menu_colors() -> dict[str, str]`
+Returns a dictionary of colors specifically optimized for menu theming:
+```python
+{
+    "bg": "#edeeef",           # Menu background
+    "fg": "#5c616c",           # Menu text
+    "active_bg": "#0078d4",    # Hover background
+    "active_fg": "#ffffff",    # Hover text
+    "disabled_fg": "#888888"   # Disabled text
+}
+```
+
+#### `configure_menu(menu: tk.Menu) -> None`
+Applies theme colors to a specific menu widget:
+```python
+theme_manager.configure_menu(menubar)
+theme_manager.configure_menu(file_menu)
+```
+
+### Automatic Updates
+
+When themes are changed using the Theme menu:
+1. The new theme is applied to all UI components
+2. The menu setup is refreshed (`_setup_menu()` is called)
+3. All menus are automatically re-themed with the new colors
+
+## Usage Example
+
+```python
+# Create menu
+menubar = tk.Menu(root)
+file_menu = tk.Menu(menubar, tearoff=0)
+
+# Apply theming
+theme_manager.configure_menu(menubar)
+theme_manager.configure_menu(file_menu)
+
+# Menus will now match the current theme
+```
+
+## Color Calculation
+
+The menu background color is automatically calculated based on the main theme:
+
+- **Light themes**: Menu background is made slightly darker than the main background
+- **Dark themes**: Menu background is made slightly lighter than the main background
+
+This provides subtle visual distinction while maintaining theme consistency.
+
+## Supported Themes
+
+Menu theming works with all available themes:
+- arc
+- equilux
+- adapta
+- yaru
+- ubuntu
+- plastik
+- breeze
+- elegance
+
+## Testing
+
+A test script is available to verify menu theming functionality:
+
+```bash
+cd /home/will/Code/thechart
+.venv/bin/python scripts/test_menu_theming.py
+```
+
+This script creates a test window with menus that can be used to verify theming across different themes.

+# Version Management
+
+This project uses automatic version synchronization between the `.env` file and `pyproject.toml`.
+
+## Overview
+
+The version is maintained in the `.env` file as the single source of truth, and automatically synchronized to `pyproject.toml` using the provided script.
+
+## Files Involved
+
+- **`.env`**: Contains `VERSION="x.y.z"` - the authoritative version source
+- **`pyproject.toml`**: Contains `version = "x.y.z"` in the `[project]` section
+- **`uv.lock`**: Lock file updated automatically to reflect version changes
+- **`scripts/update_version.py`**: Python script that reads from `.env` and updates both files
+
+## Usage
+
+### Manual Update
+
+```bash
+# Update pyproject.toml version from .env (and sync uv.lock)
+python scripts/update_version.py
+
+# Or use the Makefile target
+make update-version
+
+# Skip uv.lock update if needed
+python scripts/update_version.py --skip-uv-lock
+make update-version-only
+```
+
+### Automatic Update
+
+The script can be integrated into your development workflow in several ways:
+
+1. **Before builds**: Run `make update-version` before building
+2. **In CI/CD**: Add the script to your deployment pipeline
+3. **As a pre-commit hook**: Add to `.pre-commit-config.yaml` (optional)
+
+### Workflow
+
+1. **Update the version**: Edit the `VERSION` variable in `.env`
+2. **Synchronize**: Run `make update-version` or `python scripts/update_version.py`
+3. **Verify**: All files now have the same version (`.env`, `pyproject.toml`, `uv.lock`)
+4. **Commit**: All files can be committed together
+
+## Examples
+
+```bash
+# Change version in .env
+echo 'VERSION="1.14.0"' > .env  # (update just the VERSION line)
+
+# Sync to pyproject.toml and uv.lock
+make update-version
+
+# Result: All files now have version 1.14.0
+```
+
+## Script Features
+
+- **Comprehensive updates**: Updates both `pyproject.toml` and `uv.lock` automatically
+- **Precise targeting**: Only updates the `version` field in the `[project]` section
+- **Safe operation**: Leaves other version fields untouched (`minversion`, `target-version`, etc.)
+- **Flexible options**: Can skip `uv.lock` update with `--skip-uv-lock` flag
+- **Error handling**: Validates file existence, uv installation, and command success
+- **Safety checks**: Shows current vs new version before changing
+- **Idempotent**: Safe to run multiple times
+- **Minimal dependencies**: Only uses Python standard library + uv
+- **Clear output**: Shows exactly what changed
+
+## Integration
+
+The script is designed to be:
+- **Fast**: Minimal overhead for CI/CD pipelines
+- **Reliable**: Robust error handling and validation
+- **Flexible**: Can be called from Make, CI, or manually
+- **Maintainable**: Clear code with type hints and documentation

+## ⚠️ Important: Test Structure Changed
+
+The individual test scripts in this directory have been **consolidated** into a unified
+test suite.
+
+### Old Structure (Deprecated)
+- `test_note_saving.py`
+- `test_update_entry.py`
+- `test_keyboard_shortcuts.py`
+- `test_theme_changing.py`
+- `test_menu_theming.py`
+
+### New Structure (Current)
+All functionality is now in:
+- `tests/test_integration.py` - Comprehensive integration tests
+- `tests/test_*.py` - Unit tests for specific modules
+- `scripts/run_tests.py` - Main test runner
+- `scripts/quick_test.py` - Quick test runner for specific categories
+
+### How to Run Tests
+
+#### Run All Tests
+```bash
+cd /home/will/Code/thechart
+.venv/bin/python scripts/run_tests.py
+```
+
+#### Run Specific Test Categories
+```bash
+# Unit tests only
+.venv/bin/python scripts/quick_test.py unit
+
+# Integration tests only
+.venv/bin/python scripts/quick_test.py integration
+
+# Theme-related tests only
+.venv/bin/python scripts/quick_test.py theme
+```
+
+#### Run Individual Test Classes
+```bash
+# Run specific integration test
+.venv/bin/python -m pytest tests/test_integration.py::TestIntegrationSuite::
+test_theme_changing_functionality -v
+
+# Run all theme manager tests
+.venv/bin/python -m pytest tests/test_theme_manager.py -v
+```
+
+### Migration Benefits
+1. **Unified Structure**: All tests use the same pytest framework
+2. **Better Organization**: Related tests grouped together
+3. **Improved Coverage**: Integrated coverage reporting
+4. **Faster Execution**: Optimized test setup and teardown
+5. **Better CI/CD**: Easier to integrate with automated testing
+
+### Backwards Compatibility
+The old `integration_test.py` script is still available and called by the new test
+runner for backwards compatibility.

+## 📁 Current Structure
+
+### Active Scripts
+
+#### `run_tests.py` 🎯
+**Main test runner** - executes the complete test suite with coverage reporting.
+- Runs unit tests with coverage
+- Runs integration tests
+- Runs legacy integration tests for backwards compatibility
+- Provides comprehensive test summary
+
+#### `quick_test.py` ⚡
+**Quick test runner** - for specific test categories during development.
+- `unit` - Fast unit tests only
+- `integration` - Integration tests only
+- `theme` - Theme-related functionality tests
+- `all` - Complete test suite
+
+#### `integration_test.py` 🔄
+**Legacy integration test** - maintained for backwards compatibility.
+- Tests export system functionality
+- No GUI dependencies
+- Called automatically by the main test runner
+
+### Test Organization
+
+#### Unit Tests (`/tests/`)
+- `test_*.py` - Individual module tests
+- Uses pytest framework
+- Fast execution, isolated tests
+- Coverage reporting enabled
+
+#### Integration Tests (`tests/test_integration.py`)
+- **Consolidated integration test suite**
+- Tests complete workflows and interactions
+- Includes functionality from old standalone scripts:
+  - Note saving and retrieval
+  - Entry updates and validation
+  - Theme changing functionality
+  - Keyboard shortcuts binding
+  - Menu theming integration
+  - Export system testing
+  - Data validation and error handling
+
+## 🔄 Migration from Old Structure
+
+The old individual test scripts have been **consolidated** into the unified test suite:
+
+| Old Script | New Location | How to Run |
+|------------|--------------|------------|
+| `test_note_saving.py` | `tests/test_integration.py::test_note_saving_functionality` |
+`quick_test.py integration` |
+| `test_update_entry.py` | `tests/test_integration.py::test_entry_update_functionality`
+| `quick_test.py integration` |
+| `test_keyboard_shortcuts.py` | `tests/test_integration.py::
+test_keyboard_shortcuts_binding` | `quick_test.py integration` |
+| `test_theme_changing.py` | `tests/test_integration.py::
+test_theme_changing_functionality` | `quick_test.py theme` |
+| `test_menu_theming.py` | `tests/test_integration.py::test_menu_theming_integration` |
+`quick_test.py theme` |
+
+### Benefits of New Structure
+1. **Unified Framework**: All tests use pytest
+2. **Better Organization**: Related tests grouped logically
+3. **Improved Performance**: Optimized setup/teardown
+4. **Coverage Reporting**: Integrated coverage analysis
+5. **CI/CD Ready**: Easier automation and integration
+
