Desktop #UX has been stagnant for well over a decade. We've stopped innovating, despite desktops having huge advantages over mobile in input, windowing, and file systems. There's so much potential for improvement, from better file management, to better history, to new windowing approaches.
Besides cross-device features (like MacOS Continuity and shared clipboard), has any truly desktop-ONLY feature meaningfully changed your workflow? My theory is that nothing has but please correct me.
