Well, let's try.
I'm new (well, not THAT new) to Osu! and those are the things I found the game lacks - two technical modes.
Normalize
Sometimes mappers can get a creative with the style of their buttons and spinners - sometimes too creative. So there should be a mode that changes all buttons, spinners etc. to normal Osu! ones. This way you can play some of the songs without worrying about transparent, hard-to-see buttons, useful especially should you go for an SS.
Perfectionist
Well, same as Sudden Death, but you lose if you hit anything but a 300. Kind of obvious thing, for people that want to go for SS.
