Editor & UI Enhancement Suite

New Features

• Collapsible File Tree — A traditional tree view for navigating files with single-click expand/collapse. Can be toggled via Settings → File Tree. When active, breadcrumbs and back
  buttons are automatically hidden for a cleaner workspace.
• Improved Search (Ctrl+F) — The cursor now correctly jumps to the search bar when opening search in the code editor. Three new search filters have been added:
  • Match Case (Aa) — Case-sensitive lookups
  • Whole Word (ab|) — Excludes partial matches
  • Regex (.*) — Full regular expression support with real-time syntax validation
• Syntax Themes — Five predefined themes available: Dracula, Nord, Monokai, Solarized, and One Dark.
• New UI Preset — Midnight Blue added to appearance settings.
• New Font Options — Additional font choices available in editor settings.

Improvements

• Large File Protection — A confirmation dialog is now shown before downloading potentially large files (.db, .sqlite, .zip) to prevent accidental transfers.
