I think a gimble or transform widget would be quite useful too especially since I find myself often manipulating points on surfaces and curves and it would be nice to have something larger to grab onto than just a point (especially when you have a lot of them in your scene).

I find the edit frame one of MoI's really great features, but once you rotate the object the edit frame does not align with it anymore it stays in world space instead of local coordinate system.

Anyway some more suggestions for the v3 or 4 wish list.
