@cd-FileX nnot sure why this would be needed. You can already "unselect" transformations.
Maybe i am not understanding which transformations you are talking about

[cd-FileX]

About batch editing/transformation, so editing multiple images at once

@cd-FileX ok i see now. Not sure how an undo would work. Not easy to implement

[cd-FileX]

I guess you would have to track which images were changed and what changes were made.
Also, if there is not already one, you should save a config file or data of every image.
Then you can take this data and mark the option in the multiple transformation dialogue.
Else you could also just do it with a switch, so images which have the transformation but the switch is toggled off, get the transformation removed. The other way around if it is turned on the transformation in being added.

Yes i would have to track more history for image because of consecutive changes. I dont think it is worth it. Hope you understand

[cd-FileX]

I understand it too well that it's a lot of work.
But if you could implement that switch thing I mentioned before, that would also solve this problem.

@cd-FileX i dont sée what it would solve. There is never a case where an image is marked as transformed while not being transfromed, or the contrary. Even when it crashes!
I am.sorry i dont sée what the issue really is except from the crash.
You can always untransform images by selecting transform images and do it with all unselected

[cd-FileX]

Ah, just didn't know that... '^^
Maybe in this case a switch would make this just more obvious, though there is no problem anymore. Thanks for your help

[farfromrefug]

@cd-FileX you are right I could make it easier to understand

[farfromrefug]

@cd-FileX there is now a reset button so you know what you are doing
