    tmux-plugins/tmux-maildir-counter - Sadly, this plugin is no longer being developed. Maildir is still active, and eventually I would like to use a textual mail client (like mutt) to report a daily rundown of all the things going on the server in the Maildir format to internally log activities. It's just not going to happen with this plugin.
