Feature request: set tmux window title to 'frame-title' formatted string

[pataquets]

Just found emamux and found it very useful. Thanks for sharing.

Tried looking for a function like 'set-window-title' or the like in emamux: namespace, but found nothing. Such a function would already be useful on its own, I guess. Add the code/function which would hook where appropriate and a setting variable to enable the feature and I think it's good to go.

So far, just found how to do it:

(emamux:tmux-run-command nil "select-pane" "-T" "Title string")

Will try to wrap that in a fn and hook it to buffer change events to update it. Also, check for tmux running.
