Hi Michael,

Thanks for your elucidation.

I'll remind you about the Alt + RMB option for panning when V4 is ready for testing, many thanks in advance.

The reverse option I meant was for the zoom direction and is already there, sorry for my unclear formulation. I meant to say that the option should remain intact. :)

Your variation of the ZBrush one-modifier-key double-action sounds good too. But I can imagine it can become confusing, and doesn't fit the straightforwardness you've successfully kept intact for MoI controls.
