That's certainly possible. I'll show a demo when I get a chance.

The only thing missing atm is the possibility to define a "drag" event in editmode for scaling the scalar. That's why I put it in runmode on the other demo.

@jancsika That'll work. I'd start with that, and then it sounds like you plan to add the drag functionality in edit mode at some point, which could make it that much better, but still cool til then
