Today I finally fixed a fragile piece of how I work which is how I refer back to emails relating to long-running tasks or just ones I might want to refer back to at some point.
Thanks to the Message-Id header in every email, #Thunderbird supporting a way to find and open messages by their ID (as well as a handy add-on for retrieving them), and some #Neovim magic, I can now link to emails in my work log files and get back to them incredibly quickly and easily.
