Fantastic! I was just about to request this, for use in correcting perspective in photos. The current Perspective plug-in does not work for me, so I always had to do it in GIMP which I can now uninstall .
But I would agree with the poster who said we need an "Undo", at least one level, if not more.
Great stuff, I will make a donation soon.
Thanks,
Mick Berg.
