Hi, I'm wondering if maybe if you could take in considering adding these ideas - A 3rd gradient, because at the time there's only 2 black colour for notes (This could be useful when using backgrounds like here) -----> Hotkeys for next song (shift+N or N), Pause/Play (shift+P or P), Reverse (Shift+R or R) etc. On the opening screen, you could add a button to show the new things for the newest update. Example: Version 1.23: Bug Fixes etc. Using arrow keys to change pieces/songs when in the Save files/pieces section. As an example, arrow up could be the previous piece, and shift+up could be the previous save file.
