I have a simple 2D rectangle that's not in alignment with its shell selector and extents. Its rotated about 20 degrees inside the selector. Maybe I shouldn't be worrying about such a trivial thing, but I would like to know if there is a way to permanently turn the object's axis to align with the object. In other words, I don't want to just move the rotation arm temporarily (like with ctl-click), but to "fix" the axis so that it would be always in the direction indicated and so the selector shell would fit the rectangle. When I try moving the axis arm, it always reverts once I click on some other object.
