You say that but I’ve recently been programming an app in system 7, which isn’t totally dissimilar to 9 in UX, and I keep thinking “wow how did I ever use this.” Windows constantly occluding each other, no easy way to switch between them outside of the mouse, finder windows filled with grids that I have to scroll through, no easy way to just see the desktop, etc. Current macOS is miles ahead in usability.
