Back in the day I remember really enjoying irc inside emacs. A bunch of fun customizations there too.

magit is pretty useful! In particular, I use M-x magit-blame for blaming a file line by line and jumping to previous versions, M-x magit-status to stage individual files, M-x magit-log-buffer-file to know the file's history. Very helpful when tracking down bugs.

`M-x kill-emacs` low key slaps, no cap.
