Definitely interested in something like this - love ghostty and I’ve been finding Zellij a bit crashy recently (plus I don’t really need tabs).
screen actually works the same way architecturally: it parses all output through its own built-in terminal emulator and redraws from that state on reattach. But that emulator is decades old and lags far behind what modern programs emit. Whatever it doesn't understand gets dropped or mangled on redraw. boo swaps that layer for libghostty-vt, Ghostty's VT core, so the saved state matches what your terminal would actually display, and terminal queries get answered while detached so TUIs don't hang unattended.
tmux is great, it was just never the model I wanted. I really liked screen's simplicity, sessions and a prefix key and nothing else to learn, and boo keeps exactly that.
Very similar, based on libghostty
I currently use tmux. Not because I need to multiplex shells in a remote server, but because I like to have my sessions persisted in my local machine. Even between reboots (technically not the same session, but the same tabs and splits I had). I currently have that with tmux and a tmux plugin that restores my sessions. But I think that tmux is overkill for this. And if I'm in a tmux session, then I can't use my terminal emulator's native tabs and splits. Does anyone have a recommendation of how to handle only terminal sessions on Linux?
This no good ;)
Old busted screen can do multiple windows per session.
