Niri introduced scroll-based window management to me and it instantly clicked. I'm very happy to see a full-on Niri per-workspace emulation mode in OmniWM[1] for the Mac, recently and thankfully made compatible with Sequoia. It immediately became my main window manager.
https://github.com/karinushka/paneru is much more Niri like. I tried both but OmniWM just overwhelmed me with its options and noisy animations while paneru is very smooth, more stable and non-intrusive feeling like niri.
this. I really enjoyed the Niri approach when I discovered it and missed something similar for my mac. This is the best implementation I have tested so far, and while there are definitely some quirks, at least in my case I feel it completely usable as a daily driver(love the tabbed columns)
kudos to maintainer and contributors
