Great topic, Steve.
In addition to what has already been suggested...
A 1/2 bar fill button to allow for songs with the odd 2 beat/bar in a 4 beat/bar tune.
The DSP variation button moved to the left hand side of the panel, and within easy reach...as of now it is practically useless situated on the far right near the top.
The modulation wheel assignable to the DSP variation.
