UI3: Option to use steppers for adjusting values

The UI experience with Figma U13 would really benefit significantly if it replaces the double-sided arrow for adjusting numerical input values with an input stepper displayed as users hover over the input field.

This eliminates the need to move the mouse or reach for the keyboard, making the experience more user-friendly.

The option can also be provided as an alternative for users who prefer to use drag handles.
