I'm waiting mostly for the GED version which integrates directly into WED.
And I'd like to have better movement behaviour in the current 3d window. The jerky camera movement and keys getting locked (permanent rotation) REALLY annoy me when trying to fix something in 3D.

Ah right, a default shortcut set, clearly explained in some document would be cool as well. Currently you have to set it up yourself. That's ok, but a default would be nicer.
