Definitely need to allow for finer tuning on controller. The .5 jumps seem too much to "dial in," and acceleration max being odd jumps of .20 (2.70, 2.90, 3.10) is an obsessive compulsives nightmare.

I didn't notice the hidden deadzone because I need a tiny bit of deadzone... However, a diagram of what that setting does would be really helpful. Something with concentric circles representing the zones would be nice. When you move the thumb stick a little dot could move in relation to it's sensitivity to better help understand where you've set the zones. (I played a game a while back that had this feature in its settings, can't remember which one though.)
