Yay!! I've been hoping for this functionality, which also has been discussed
over at IRC. Thanks, Jon!

With my very basic elisp knowledge, I've tried to adapt this to the search (and
unthreaded) views, with no luck. I have trouble understanding the face part.
Since afaik in the search and unthreaded views there's no change in face for
matching messages, I thought I could get away by removing that part. But this
doesn't work:

(defun inwit/notmuch-search-authors-or-to (format-string result)
  (let* ((headers (plist-get result :headers))
         (to (plist-get headers :To))
         (author (plist-get headers :From)))
   (format format-string
        (if (string-match "inwit" author)
        (concat "To: " (notmuch-tree-clean-address to))
                      author))))

(setq notmuch-search-result-format
     '(("date" . "%12s ")
       ("count" . "%-7s ")
       (inwit/notmuch-search-authors-or-to . "%-20s")
       ("subject" . "%s ")
       ("tags" . "(%s)")))

Any help would be greatly appreciated.
