Adds directory grouping (press 't') to organize files by directory structure with folder headers. - Added 't' keybinding to toggle directory grouping - Files are sorted and grouped by directory when enabled - Smart path truncation for long directory names - Status bar shows 't:tree' hint
- Add FileTreeItem enum and expanded_dirs state to App - Use Space to select files and expand/collapse directories - Use o/O to expand/collapse all directories - Underline styling for selected items - Tree structure with ▾/▸ icons for expanded/collapsed dirs - Auto-expand parent directories when jumping to file - Sync selection when navigating between panels - Add 7 unit tests for tree functionality
