When I moved from x to Wayland; I just moved from my bswpm setup to plasma because I couldn't get similar workflow that I set up in bspwm in either hyprland or sway. Then river entered my radar; but I think the development moved towards becoming a protocol rather than a WM. Nice to see river being used, might give this a try.

I knee-jerk moved to Noctalia because the Mango functionality was broken (due to config syntax change). Guess is a good opportunity to switch back.

Funny you say that, I just started doing specs, planning for a river based compositor based on Niri & Umbriel. After mentioning the idea a couple months ago. https://news.ycombinator.com/item?id=49093022

Umbriel is a Niri- like scrolling wm from the Noctalia devs, have really been enjoying it. But I do want something more configurable, easier to play with. And river certainly seems like the main go-to base for that.

Running Noctalia is a must for me. It's a great shell, from a great team. The v5 took a lot of lessons from the past & really spun a very elegant beautiful new user product with a great architecture. Great stuff, not to be missed imo. Happy convert from DMS too.
