Hi Neptix, you can do MMB for Rotate by a setting in MoI under Options > View > "Rotate/Pan/Zoom options" > "Rotate with middle button" checkbox.

But sorry there isn't any way to do Shift+MMB for Pan or Ctrl+MMB for Zoom currently.

If you set "Rotate with middle button" then you'll have:

MMB for Rotate
RMB for Pan
Ctrl+RMB for Zoom
