Being able to rotate or mirror the source selection for the patch-tool would be very useful when the image has lots of symmetric texture (like in a carpet). I was shooting a very untidy apartment and we had to move the trash back and forth to keep them out of the cameras field of view. Later on Photoshop I noticed on one image, that there was a piece of trash in the carpet that I had missed during the shoot. The carpet had an identical spot, but it had to be rotated 180-degrees. It would be handy if patch-tool could do this with a push of a button.
