protecting a history stack
After I have optimized an image and produced a certain history stack, I often find myself to re-enter the image after
a few days. Then I tend to tweak it even a bit further, but often I fail. Sometimes I even lose my previous work by doing
unwise settings :(
It would be nice to have a "protect" button in lighttable mode. If applied to an image the current history stack is protected.
Whenever I decide later to work on the image again and change settings this should automatically generate a duplicate. This way
I could always go back to my previous image.
Of course this is an option to protect a user from himself. However, being a stupid user I would really profit from that.
