This may be asking for a bit much, but here goes nothing. The ability to create custom character icons or/and icons corresponding to their respective characters , custom arrow designs, the ability to change gf to a custom one, favorite songs so you don't have to constantly scroll for the ones you want, and maybe custom pose/taunt animations would be cool as hell, some mods won't have it, but hey, why not just make it a png of a funny meme. I don't think I mentioned these in my previous suggestion but here it goes, being able to test the character's arrows animations to see if their matching, the ability to go back and change the chosen animations. And that would be it, It'd be really cool to see these features in the distant future.
