Merge 5ebb36077a into 760af804c0

This commit introduces a comprehensive Tree Search feature, including:
- Tree highlighting: Highlights items that match the search query.
- Counting descendants: Shows the number of matching items within collapsed branches.
- Jump to next match: on enter.
- (Limbo-)Shortcut: Default CTRL-F.
- Menu entry: Misc->Search Tree.
- Remember separate SearchInfo for each tab.

Key implementation details:
- Optimized performance for large trees
- Implemented recursive filtering for efficiency
- Added UI elements including next/previous match buttons

Development History:
- Initial implementation of highlighting and filtering
- Multiple rounds of performance optimization
- Bug fixes and refactoring for correctness
- UI enhancements and polish
- Code cleanup and style improvements
