I have some recommendations that would def make this mod a bit better
1. add a delay before a character sings after theyre placed while no other characters are on the roster
2. add a feature where trying to remove a character when the loop is about to end makes the character just be removed at the end of the loop, same thing with the solo/un-solo and mute/unmute button
3. make all other characters unmute after a character was removed after singing solo/while all others are muted
4. dont make the extra buttons retreat after clicking away from them
of course all of these are just recommendations and i know unity is quite difficult, the mod is still quite cool and unique!!!
