> A really useful feature on MacOS is that you can scroll a window that doesn't have focus by hovering over it and using a mouse with a scroll wheel/surface.
Yeah, Windows has had that too for a while now. Dunno for sure how long; some five years (or eight? Ten?), I'd guess.
Citrix (a remote desktop app) breaks that; apparently no mouse scrolls are sent to an app on the remote desktop until you click in the Citrix window.. Thunderbird partially breaks it: I just tried with TBird in the background: scrolling the list of emails (that works) and the text of a selected email (does not work).
