I have PA900 and I don't know if my suggestion is applying to PA3X but these are my wishes as a PA900 owner:
Adding light-emitting diode (LED) to the Transpose buttons (very convenient to monitor if the keyboard is transposed or not on a bad lighting condition) and Assignable Switches (ex; specially when one of the Assignable switch is set to micro-tuning). That could be very convenient in the live performance in a low lighting condition on stage.

this seems reasonable.
