This sounds very interesting. I'm currently in the middle of revisiting my desktop setup and interaction style. Landed on Qtile/Wayland but now I'm starting to notice lag.

> Every monitor has its own separate window strip. Windows can never "overflow" onto an adjacent monitor

I'm someone who was very content with the constraint of a laptop (one single screen, generally running one maximized window per workspace and switching with F-keys), but has never really become comfortable with multi-monitors. Can anyone explain why window managers always default to treating individual monitors as completely separate entities rather than one larger screen that works together? Like I would have thought the default here would be to have two monitors operate on the same horizontally-scrolling set of windows. Either tied together, or as independent viewports. But everybody always seems to reach towards treating each monitor as having disjoint windows. Which I guess I can get used to, it just seems odd?
