Just a small thing, but if you have a custom map with too long of a title AND the folder it's in has enough maps to need a vertical scrollbar, it cuts off the start of every map title in the list
↓ overflow w/o scrollbar

↓ overflow w/ scrollbar

Would it be an easy fix to make multiple inputs at once on the same side work? It doesn't currently register when you try to play any more notes on one side if another key for that side is being pressed, and I feel like it would be useful and allow people to create harder maps if that were not the case. I totally understand if that's too much of an ask or if it's just not a priority btw, you seem busy with other stuff lmao
