I agree with you, Ivan. I also use a fake operation to create the proper steps
in the history (usually, I just toggle the over/underexposed indicator). I
don't know what would be the ideal solution. This problem is a consequence of
the fact that changes are applied live, without an "OK" button. It would be
nice to have real undo, especially with the modules that don't take numerical
inputs (Tone curve, Color zones etc.). It's almost impossible to restore a
curve perfectly, and that discourages experimentation.
