[REQUEST]ALTERNATIVE NUMBER INPUT

The default number input for vx ace is jarring and visually unappealing, but I still need a way to input numbers for a battle system. What I was thinking was a number input where left and right arrows would increase or decrease the value by one, instead of using digits and up/down arrows, since they're all going to be small numbers (<20)anyway. I'd like it to go negative as well, which should theoretically be possible. If something similar to a scale input exists, that would be fine as well.
