feature request - navigation

 From:  PaulT

At the moment the navigation works almost as I would expect apart from the zoom control. Would it be possible for there to be an option for alt+right button be the zoom control, rather than/as well as alt+ctrl+right? Maya and a lot of other applications use, or allow the use of the alt+left=rotate, alt+mid=pan, alt+right=zoom configuration. At the moment it can be a little frustrating when working back and too between applications.

Also when zoomed in it can be a pain trying to keep a part in the view when trying to rotate around it. The ability to centre over a particular part or point on the model would make a huge improvement.
