Suggestion for added function in VWD:

SHIFT key emulation button.

Sometimes I have had to hold the SHIFT button for up to thirty minutes while working with the Dynamic Deformation tool. It would be nice to have a button that emulates holding the SHIFT key for when one is using it for long durations. People would then have a choice of holding SHIFT for quick bursts of pulling, and clicking a button that keeps DD active until the button is clicked again stopping the emulation.

I created a quick script in Blender Python that does this for view-port controls, so I think it should be an easy thing to implement in VWD.
