There was a discussion on Facebook about nudging channel faders. It can be hard to get some fine control over a channel, especially when you are in a hurry and doing something else like playing drums or piano.
It might be a cool feature to have a "nudge" function for the faders, either by tapping above or below the fader handle, or by tapping the top or bottom of the fader handle.
