I'm a bit lost on what OP is complaining about. I agree that GNOME has tons of flaws, and they make some design choices that are questionable, but the 3-button titlebar click sending the window to the back of the Z-stack and being able to copy two things at once (one via clipboard, one via middle-clicking) works fine for me on GNOME 3.36. Am I missing something? Or maybe GNOME 40 screwed things up?
