The beginning of what I hope can be a useful integration: send mails to
taskwarrior as tasks and open the corresponding mail from tasks in
taskwarrior.
To make a task out of an e-mail, in neomutt, simply press `t` when the
mail is selected or opened. It will create an automatic task in
taskwarrior with the description "Reply to [mail] by [sender]" and tag
it as mail.
If you press `T` instead, you can give the task your own description and
tags.
In taskwarrior, you can simply `t open <taskid>` on a task that came
from neomutt to show the message content on the command line (using
notmuch). This is still a bit rudimentary and I would like an improved
display, but it works for now.
