Right now, hotkeys to change what sampleset and addition you're in is set to shift/ctrl + q/w/e/r. That makes perfect sense for qwertz/qwerty users, but everyone else is pretty much screwed. My proposal would be to default them to whatever you've set nc/whistle/finish/clap to in the options, so they remain unchanged for qwerty/qwertz users, but become usable for users of alternative keyboard layouts. I'm personally using a custom keyboard layout and can't really use hitsound hotkeys without switching layouts. If we can't customize advanced hotkeys (which at some point I would love to be able to), at least let us have this as a quick fix.
