Major UI improvements addressing user feedback:
1. Color-Coordinated Syntax Highlighting
- Command names: Bright cyan + bold
- [OPTIONS]/[OPTION]: Yellow
- UPPERCASE args (FILE, PATH, STRING): Magenta
- Lowercase optional args: Green
- Ellipsis (...): Dim white
- Applied to both interactive menu and explain mode
2. Fixed Clipping Bug in Interactive Menu
- Recalculated width allocations more conservatively
- Changed to percentage-based DESC_WIDTH (40% of terminal)
- Added min/max caps for widths
- Improved spacing calculation (TERM_WIDTH - VISIBLE_WIDTH - 8)
- Added safety bounds (min 3, max 20 spaces)
- Syntax now always visible (truncated with ... if needed)
3. Redesigned Flag Browser for Better UX
- Eliminated wasted dead space above fzf
- Integrated syntax and description INTO fzf header
- Created elegant box header with command info:
- Command name
- Colorized syntax
- Description
- Height increased to 95% for more flags visible
- Preview window reduced to down:3:wrap
- Removed echo spam ("Extracting flags...", "Found X flags...")
- Clean, immediate transition to flag browser
4. Updated Function Signatures
- show_flags() now accepts: cmd_name, syntax, description
- browse_flags_fuzzy() now accepts: cmd_name, syntax, description
- Interactive mode passes all three parameters
- Explain mode uses colorize_syntax() function
5. New Functions
- colorize_syntax(): Parse and colorize syntax by element type
- Applied consistently across all display modes
User Experience Improvements:
- ✅ No more clipping - syntax always visible
- ✅ Instant recognition of parameter types via color
- ✅ No wasted screen space before flag browser
- ✅ Command info integrated cleanly in fzf interface
- ✅ Professional, color-coordinated appearance
Technical Details:
- Width calculation: DESC (40% terminal), SYNTAX (remaining - 25)
- Safety bounds on all width calculations
- Color coordination: cyan/yellow/magenta/green/dim
- Consistent formatting across interactive and explain modes
