Just tried the new edit mode. I like it, makes some things simpler.
The only things I can think of to change at the moment:
1. Make the edit mode window pop up on the right side, as it covers the data on the left side.
2. Switch the functionality of the left and right mouse buttons. Seems counter-intuitive the way it is now with left-click doing mouse look and right-click selecting objects.
3. Add in some way to move more quickly around. Larger scenes can be a pain to navigate with the slow movement speed. Perhaps just have the Shift key make the camera move 3X as fast (or more) while held.
