More of a UX change, but @GIMP now notifies you of unsupported features when importing PSDs! The goal of course is to make this list smaller, but until then users should be more aware of potential issues.
@zemarmot mentioned the UI could look better, so suggestions for further improvements are welcome!
@CmykStudent @GIMP @zemarmot do you first evaluate which of these are applicable so that you can hide the rest?
