Agreed. Rotation is the bigger pain.

In LEdit, I occasionally add an imaginary new piece, "rotate.dat", after the
piece I want to rotate. Move it to the point where I want it, then set the
rotation on that point. Move back up a line to the real piece and rotate.
Then delete the imaginary piece.

We have used "male" and "female" before. We have also used 1 and 2 finger.
The 'finger' method seems to be used for items that can have more than 2

than 'male/female'.

| (...) The center should be on the rotation point. Like you said, rotating the pieces when the rotation point is not centered on the hinge is a bigger pain than getting the pieces into the right position.
