I think if you guys added additional skin options ( 1-3) it will not only make djay look more versatile and appealing, but when your in the dark, whether it be the dj booth, your room, a studio etc, I think an option for brighter and neon looking colors would be awesome as they would shine on and reflect off your midi controller. Gets you in the zone, brings a certain vibe and makes it a full out party.
Also, any plans for 4 channel control? Maybe bigger waveforms for more accurate cuing and drops when using sfx.
