Let us do more with Shift/Ctrl/Alt/Space+Mouse-R/L. So far just smooth terrain works with shift and Space+Mouse changes height though the sensitivity is too low.

Not just for camera viewing, also for changing between Select/Move/Rotate objects and Raise/Lower/Flatten/Smooth terrain would be usefull to have comninations of keys and mouse(keys)

Hopefully there will be a plugin interface. I remember a lot of useful plugins for NWN2 toolset back in the days.
