On the actual thread topic, I guess Wio is cool. If it works as well as I think it does, I shall have to improve my opinion of Wayland.

The developer of wio is the same that wrote sway (an i3-like Wayland compositor) and wlroots, which is now used by many projects. Sway is definitely a really nice environment to work in.

Stray thought: Why didn't the suckless folk ever use Xnest instead of mucking about with things which require application support? Not that Xnest has worked 100% for years, but they could have tried to fix it. I mentioned it to them but they were already hyped up about tabbed.

I would say that I prefer a tabbed+tiled environment and would love a Rio variant that behaves like i3 or DWM with workspaces and tiling (dmenu does not make sense on Plan9 due to namespaces - so execution from terminal windows like in Rio would still be the same).

If I am making a "laundry list" of wishes I would also love such an interface to be based on the solarized colour schemes (dark, light).
