"""
Test script to verify that UI flickering when scrolling has been reduced.

This script documents the specific improvements made to reduce UI flickering:

1. **Auto-save callback optimization**: Removed unnecessary data refresh from auto-save
2. **Debounced filter updates**: Added 300ms debouncing to search/filter changes
3. **Efficient tree updates**: Improved tree refresh with scroll position preservation
4. **Optimized scroll handling**: Enhanced scrollbar update logic to reduce frequency
5. **Batch operations**: Used update_idletasks for smoother UI updates

The changes should result in:
- Smoother scrolling without visible flicker
- Reduced CPU usage during scroll operations
- Better responsiveness when typing in search fields
- No more interruptions from auto-save during user interaction
