+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 (`src/main.py`)
+```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 (`src/search_filter_ui.py`)
+- 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 (`src/main.py`)
+- 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 (`src/main.py`)
+- 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 (`src/ui_manager.py`)
+- 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. `src/main.py` - Auto-save optimization and efficient tree updates
+2. `src/search_filter_ui.py` - Debounced filter updates
+3. `src/ui_manager.py` - 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.

+# 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
