It would be nice if IC Pro could be made to work with WaveLab/WaveLab Elements aswell. Yes, I know that it's meant for Cubase, but so is the CC121 and that can be used to control WL/WLE, never the less.
The fader sections (with maybe the exception if the Master Fader) is of cause of little use when it comes to controlling WL/WLE.
However, the Transport Controls and the Key Commands windows would be very useful in controlling WL/WLE.
A "SKI Remote" for WL/WLE. Maybe something to think about.
