I think it would be cool if "Select a kit" was a feature. Each kit would require a certain permission. That way while regular users get access to- lets say 3 different kits, streamers and donators would get access to 5 or so kits. When a player selects a kit, they only get that kit. That goes for everyone. They're allowed to switch the kit they want to get for ingame, although they aren't able to receive multiple kits-- if that makes sense. If this were to become a thing, it would also be nice if kits got their own config. That way pre-existing settings won't have to be redone, another config is added. and the jar just needs to be changed out.
