I am used to the old school version of Photoshop, back from 2011, which is a dark background. I just upgraded. The newer one is gray and bothers my eyes when I'm editing. How can I change PS to a dark theme?
. . . . Just to be clear, you can only change the color of the canvas for an open file. If you right-click on an empty workspace, nothing will happen. I believe it was different back in the days of Elements 8(?), when you could change the whole workspace area theme.
