Hi, Pavel.  It wouldn't be hard to put together something like you're
suggesting with the current functionality:

* add a key binding to add the tag "mark" to a message.  In emacs:

(define-key notmuch-search-mode-map "q"
  (lambda ()
    "mark thread."
    (interactive)
    (notmuch-search-tag "+marked")))

* add a key binding that runs "notmuch tag $TAG_CHANGES -- tag:mark":

(define-key notmuch-search-mode-map "Q"
  (lambda ()
    "apply operation to marked threads."
    (interactive)
    (notmuch-tag "tag:marked" nil)))

That last function should prompt for tags to apply to the marked
threads.

Note: those functions are NOT TESTED, and require 0.13 (which is not
released yet).

hth.

jamie.
