Command ("/ghostoff") to forcible, and persistently, disables visible ghosts until you enter the counter command ("/ghoston").

The idea was entirely Phileryno's, presented here, and the implementation was quite a bit trickier than I had thought.

Edit: Fixed the edit mode problem, and updated the attached script.

Did not think of that, which is kinda silly. But I think I fixed it now (updated the script in the thread starter), and you should be ghost-free in editing mode. Thanks for pointing it out.
