I agree. The distro I am using lets me move windows by holding down Meta/Super key and left mouse button - anywhere in the window. Firefox is an example of how terrible it can get, see this screenshot: https://i.imgur.com/zs2wekv.png. To move this window I can either click to the left of the Firefox icon (to the left in image) or between the arrow down and minimize to the right.
Yes? We managed on 1024x768 screens and all that “wasted” real estate. Meanwhile I have two 2880x2560 monitors hanging off my dock and UX designers are tripping over themselves to hide more shit in the overflow menu to save me 5 pixels of vertical space.
