Please add the ability to zero out the rotation on object groups.
When you create a group of shapes, you have often rotated a number of them into various non-standard positions. When you group them, the group as a whole is assigned a rotation value (I assume an average of all of them). It would be nice if a group could be set so it's rotation was at 0 degrees when created.
From a design perspective, this would make rotating groups easier. Especially with snapping on.
