Sculpt Mode modyficator idea.

Hello

I have idea for mesh modification system in sculpt mode.

As we have pretty nice bones system I have wondering that could be possible somehow to use one bone in sculpt mode for streching, rotating, scaling not masked part of sculpted object.

I know it looks like Zbrush modificator gizmo, but I hope it is enough far from their idea and that could be implemented in Blender.

I waiting for respond and any comments what do you think guys. I'm not programmer so maybe some of you guys can do such of thing?

Regards

Konrad
