PROBLEM:
- History displayed ALL entries at once
- With many backups, first entries scroll off screen
- Cursor navigation worked but selection was invisible
- User had to "blindly" navigate 5+ entries to see anything
SOLUTION:
- Added viewport with max 15 visible items at once
- Viewport auto-scrolls to follow cursor position
- Scroll indicators show when there are more entries:
* "▲ More entries above..."
* "▼ X more entries below..."
- Cursor always visible within viewport
RESULT:
- ✅ Always see current selection
- ✅ Works with any number of history entries
- ✅ Clear visual feedback with scroll indicators
- ✅ Smooth navigation experience
FIXED:
- Removed unused cursor variable that was always a space
- Arrow up/down now visibly highlights selected item
- Added position counter (Viewing X/Y)
- Changed selection indicator from ">" to "→"
- Explicit cursor initialization to 0
RESULT:
- ↑/↓ keys now work and show visual feedback
- Current selection clearly visible with highlight
- Position indicator shows which item is selected
