For many people, this probably isn't very important until directory/fighter addition is a thing, however:
- It'd be nice to already have this solved once we can add new fighters, so people don't get frustrated when they can only add a couple new fighters before hitting the limit.
- Even without directory addition, there is still a use for this now. First, people would be able to separate Pyra/Mythra, Pokémon Trainer, Ice Climbers, and Giga Bowser all at once. Second, if someone also figures out and shares a way to display two CSS icons which each give the option of different alts for the same fighter, people can basically add as many Echo Fighters as they want without directory addition. For example, the Dragon Quest Heroes could take up 4 CSS slots if we had a way to say "this icon only contains c00 and c04, while this icon only contains c01 and c05", etc.
