So I installed Explorer patcher to get the old taskbar back https://github.com/valinet/ExplorerPatcher
Other than that the only feature of 11 that I have used is the snap zones. And I guess if I want that I can install the power toy it is based on.
* Cmd+~ from a fullscreen window does nothing, and non-full windows of the app cycle only among each other. If I have fullscreen windows anywhere in my setup, it breaks my flow and (afaik) makes me mouse to the Window menu. I feel like MacOS's fullscreen paradigm is more to blame here, because it violates a range of other behaviors I'd expect.
* Unlike cmd+tab, cmd+~ doesn't give me a visual overview of my windows (how many? what order?). I can see why, since cmd+tab shows only icons and app names, which isn't enough to differentiate between windows of the same app (unlike alt+tab on Windows, which shows thumbnails, paths, page titles, etc.
* Cmd+~ also cycles in a static order, not most recently used. This feels like fallout from the second point, in that if you're not showing thumbnails it could get confusing.
The first one in particular took me a bit of time to realize; before I did, it just felt broken and made me not rely on cmd+~ at all.
I've always felt like multiple desktops (on all 3 OSes) have untapped potential, but like you its never worked for me. But hope springs eternal - I try it again every now and then. I'd like to hear more about how some people use it.
Heard good things about Rectangle. I'll check it out.
UX does differ somewhat between, Linux distros & WMs (and Chrome OS, to the extent you consider it Linux proper), and between releases of all three OSes; but within families they maintain broad continuity. I use multiple variants - again daily - and my point stands that all have untapped potential.
But I doubt you supposed otherwise, nor honestly think I'm unaware of other OSes... so why take the time to ask? Pedantry? Did I slight an OS you favor?
