If there is one thing about macOS that really sucks, it is the window management. I have been using it for three months now and still don't understand how to use it.
It is not that I am inexperienced (Windows 95/98/2k/XP/Vista/7/8/10/11, Linux with all kinds of Desktops over the years (KDE 2/3/4/5/6, Gnome 2/3, Sway, Unity, XFCE, Enlightenment, blackbox, ...)), or that I didn't try (searched, watched several YouTube tutorials). I also tried different options, such as disabling the entire "Displays have separate spaces" feature (it fixes some cases, but others worsen).
My verdict is simple: They would be better off just adopting the dumb Microsoft Windows 95 approach to window management.
And it isn't that I don't like the system overall. I have never had a laptop with such superb performance, and at the same time, it stays cool as ice and silent. I love the animated video backgrounds on the lock screen with the slowdown on login, and having Zsh as the default is also fun. But the window management...
This is my exact experience! I really tried for 6 months and I just couldn't avoid fumbling around. For example, the experience of going in/out of fullscreen is jarring.
What's funny is that when someone first learns about Alt+Tab it's like the best cheat-code for any desktop navigation, but after switching to Niri, Alt+Tab seems like a silly way to layout your windows.
