I think one of the biggest features missing from the editor is the ability to properly scale/rotate groups of objects properly. At the moment, if I select a bunch of objects in the editor, and try to rotate or scale, they will all rotate and scale individually, without updating positions to keep the same initial arrangement.
I'm confident that this setup is fairly useless - I cannot really see a situation in which this would be beneficial. However, I think many users would benefit from the ability to scale and rotate groups of object properly.
How many of you agree?
