can you share more on the tmux model vs boo?
Screen is 1 server to 1 client.
In screen each client session is a fork of the screen server. In tmux there's one server and many client forks iirc.
Without -x though it works as originally described.
Edit: gnu screen 1.0 was originally released in 1987. The -x flag was released in screen 3.0 in the 90s. TIL
They also compose: a boo session is just a PTY running a program, so you can run tmux inside one if you want.
Of course, it's impossible to know for sure what was LLM processed or not, but some of your posts (like this one) are getting classified that way.
