Feature request : Multi-color balance undo

[pierrelabreche]

During use of the multi-balance tool, adding a new row of color corrections may invalidate other rows, which are displayed with an "err" indicator.

It would be convenient to offer an "undo" command ( Cntrl-z ) for reverting to the previous state of the correction curve, thus revalidating the rows that became erroneous.

You can delete the offending row with the garbage can button...

Thanks for the tip. I still like the idea to enable undo/redo ; for example, to bring back a deleted color pair.

If i were going to implement undo in Multi Color Balance, I would want to implement it in all the other transformations as well. There is a relatively simple mechanism I could use to implement this, namely saving a copy of the command line every time it changes, but this is still a whole lot of rework so for now it goes on the requested feature list.
