Zellij still can't hide/show the status bar on the fly[1] and doesn't support windows preview in the windows list mode. Just these two (and many more) things are enough to stop me from migrating from tmux.

You can't rebind plugin maps, so the session picker uses my preferred unlock chord to create a session. Dev had no interest in changing that.
