I don't have C11 installed anymore so I don't know if this is a new bug or something I never noticed before, but I'm not able to copy or paste any adjustments done on a layer/to a layer. The copy/paste icon is disabled on all tools when I have a layer selected. How come?
I can get around this by saving the adjustment as a preset on the source layer and then apply the preset on the destination layer, but it's such a bizarre limitation...
