I think it's a great idea. What I find especially nice about this, is
that it works for both, just showing the structure of one thread and the
traditional all-messages-matching-a-search view. I've actually rebound
<return> in notmuch-search to this and it works great so far:

(defun notmuch-search-pick ()
  "Show the selected thread with notmuch-pick"
  (interactive)
  (notmuch-pick (notmuch-search-find-thread-id)
		notmuch-search-query-string
		(notmuch-prettify-subject (notmuch-search-find-subject)))
  (unless (notmuch-pick-get-match)
    (notmuch-pick-next-message))
  (notmuch-pick-show-message))

Yeah, the hardcoded "black" is also pretty annoying if one uses a
black background. :)
I'll send a patch fixing that later.

Yeah, that's basically my main use case, as I don't like dozens of
messages of the same thread cluttering up all the search results
(e.g. for tag:notmuch).

Thanks for the great work David and Mark, I've really been looking
forward to something that makes my half-baked attempt at thread
outlining [1] obsolete. :)
