Nudge to Cplane?

 From:  manz
Hi Michael,

Is there any way to implement a "nudge" based on the user Cplane rather than it always defaulting to the global axis/Cplane?

While here, I would also ask for the possibility for the view rotate to be based on the Cplane rather than the global. (It can get rather disorientating when working on a user Cplane the way the view rotate defaults)
