I think some category extensions would be cool. New% could be included there (beating Any% but starting from New Babe+) and maybe the invisible maps too. Maybe also Darkness Main Babe.

that would be cool

Invisible and darkness if anything would be added to the Jump King Custom Map src site, but i wouldn't count on that because they usually only add "real" custom maps. Beating mb from new babe seems kinda useless, we have chapel+ which is good enough.

I think some category extensions would be cool. We could add stuff like new% and mushroom% to that. And it could be refreshing to try some categories like that
