Am I the only one who runs more than one terminal at a time? What happens now is I start an xterm on monitor #1 and start byobu within that. Various windows (whatever you switch amongst on pressing F3 and F4) are started - eg one might be client code running, one might be server code, one might be a database server etc. But sometimes for example I want to look at the client code output and server output simultaneously. At that point I switch byobu to the client window, and start a new terminal on monitor #2 and tail logs or whatever is appropriate. It is an annoying pain that I can't just run byobu and switch as I see fit.
In any event this is a multi-year frustration for me. People keep coming with convoluted workarounds (pointing tmux to tmux as far as I can tell) which it then isn't possible to figure out how to apply to byobu. All the while I wonder why two xterms running next to each other would ever want to be in lockstep by default?
