@a7 @icedquinn If it's filesystem-based, that'd be cool. rio is fine as a window manager, but it's just fine: the main thing it gives you is that it fits perfectly with what :bwk: called "the tools approach" and fits really well with the rest of the OS. Like, you can grep a shell window running in another session. You can mount a remote display and then start sending it events and moving windows around.

Like, on Linux, X11 fits how things work. I don't like how things work, but it fits.

I typed "arcan" into the search engine and then "arcan window manager" because a bunch of irrelevant stuff popped up and this link was purple: https://arcan-fe.com/about/ . I must have looked at it at some point. It does look like if I were to replace X with something, this would be the thing. But X is X, Linux is Linux.
