Hi Marcel,

Thank you for the feedback, especially the code review. I just copied an improved version to the inbox. Comments inline.

Done!

Had a short look and decided this was for another day. ;-) Especially since I always use fast drag. Does anyone use non-fast drag?

Done. I introduced a method.

I am not sure how to bench that. However, I moved the call to #clearArea outside the block, so it is only called once when you start dragging. This should not be a problem because I cannot think of a  way the display might be resized while you are dragging a window.

I had thought about this. This is a different feature, though.

Cheers,
