It would be awesome if there was a way to develop a broad dip switch menu.
4 options for throws: default is as in st (old characters can’t tech; new characters can tech all), hyper/ae style (old/classic throws can’t be teched; new characters can tech only new character throws), all throws techable, no throws techable
Announcer style (CPS1/CPS2)
Language audio options (mostly for Cammy and DeeJay)
CPS1 hit/block/throw sounds
Kara cancel for faster special move recoveries on/off
Wall bounce on/off
And so on.
There have been scores of ideas pitched over in the HDR forum. Not that all of them are gold, but many are just basic hitbox changes, and make a lot of sense.
EDIT: Pasky posted much more information about specifics that would probably help in his HUD thread.
