Problem
Currently, adjusting each corner increments/decrements by 1 in a constant pace even when holding the arrow buttons. When a pretty big adjustment is needed, it takes more time than necessary.
Proposed Solution
I’m aware that mouse dragging might be enabled in the future but I think it will also be better to add some kind of a “momentum” when adjusting via the arrow keys. Like if you press and hold an arrow button, the speed of the adjustment increases as time pass.
