Earlier quoted context omitted.
Yes same here but with i3, I ran it for over 10 years but niri was just an instant 'aha' moment for me. I will say, recent builds have a 'mini map' sort of zoom-out feature that I quite like - my one critique of niri was that I would sometimes get 'lost'.
One of the advantages of tilling wm are that every window that is run, is visible too. Nothing invisible exists. But in this "endless horizontal tilling" scheme, the above principle would no longer hold, right?
Things on other desktops are invisible in every WM.
The only difference with niri is the possibility for things to be left or right of the current window. Overview helps with that, but I know what I expect to be on a specific desktop (it's related to the topic) and seldom need it.
