I've always wanted to do a major redesign of the gamepad versions - one which includes all features. I know it'd be possible to do, but the problem is, since I have no experience with VC PC + Gamepad, I can't really comprehend what would (and wouldn't) be good controls.
Also, I dunno, if alot of the gamepad users have their own control setups that are quite different to each other, then that's another problem - coming up with a setup that somehow works for (at least 'almost') everyone. On the other hand however, if most gamepad users use a similar setup, then perhaps it would be possible to come up with a decent redesign which does work, and does include all features.
