+### Numpad Scaling Fix (#58)
+- ✅ Fixed "keyboard for number input has same size as letter input" complaint
+- **Horizontal scaling** (be23db40): Removed explicit `width="6.0"` from pin.xml
+  - Layout auto-computes to 5.0 units (4 keys + 1 shift margin)
+  - Keys are now 20% wider (eliminating right-side padding)
+- **Vertical scaling** (74580c22): Added `scale_numpad_height` setting
+  - When enabled and `bottom_row=false`, uses actual `keysHeight` as divisor
+  - Rows scale up to fill full keyboard height for easier tapping
+  - Theme.kt modified row_height calculation logic
