This package adds a global minor mode which allows you to bookmark
notmuch buffers via the standard Emacs bookmark functionality. A
`notmuch buffer' denotes either a notmuch tree view, a notmuch
search view or a notmuch show buffer (message view). With this
minor mode active, you can add these buffers to the standard
bookmark list and visit them, e.g. by using `bookmark-jump'.

To activate the minor mode, add something like the following to
your init file:

(use-package notmuch-bookmarks
  :after notmuch
  :config
  (notmuch-bookmarks-mode))

There is experimental support for providing annotations which count
the read and unread mails for the bookmarks. Currently, annotations
do only work when the package `marginalia' is installed. Turn on
this feature with `notmuch-bookmarks-annotation-mode'.
