i know all my fellow grumpy-about-computers folks on here are all big on the bringing back of physical buttons on Devices, so let me give a particular shout out to physical dials on monitors for brightness/contrast. god i miss those. in a room with windows to outside so the ambient light changes multiple times a day? no worries. just flick and all your problems solved. not a single submenu
