Whoooo! We are really very happy about new developers, *especially* on 
the GUI side.

Tom is the main guy for this, and he'll probably chip in.

Before you rush ahead, X/Y mode is already available through the 
'constellation' sink. But that's not to say we can't change the time 
sink. Particularly for people who are used to it.

Pause is already in QT -- check out the menu.

Yes, but don't want it to be permanent. Ideal woulde be a sidebar with 
instrumentation buttons that is collapsible, or hidable or something 
like that.

There's a couple of things we'd like to add to the QT widgets, let me 
have a look if I can find that list.
