Good to hear. Always transforming wasn't just unpreferable; it straight up broke some sections.
Recently I was playing a level as Knuckles, and there's a segment where you have to glide/climb walls over a giant bottomless pit. There are a bunch of rings in the middle of it, so if you went over 50 rings, you were fucked, because you couldn't begin a glide without turning super, and when you do, you just fall and can't glide.
