How to view keyboard and monitor images

[DRP]

I have just discovered the existence of Phantom Jester, which ought to be hugely useful in a show I'm working on at the moment. But switching between the keyboard (48) view and the monitor image is far from convenient. Is there a way of quickly toggling between the two?

 

There's a lot of black space at the top and bottom of the keyboard image. In a future release, might it be possible to shrink this window vertically so that only the keyboard is diplayed? It could then be overlaid onto the monitor image so that channel levels could be seen beneath the keyboard, or the curent scene details above it.
