Sorry about the delayed response.  Just catching up on old mailing list
stuff.

If I understand what you are looking for here, you want to filter the
messages AFTER they have been threaded.  Mark and I have discussed this
in the past, and other algorithms which are derivatives of REFERENCES
are possible.  For instance, a REFERENCES.UNSEEN algorithm would return
only those threads which contain at least one \Unseen message (similar
to Netscape's "Threads with Unread").

To do something like your last two examples, we would have to come up
with a way, either with the (upcoming?) VIEW/WINDOW extension or an
extension to THREAD, to provide generic post-thread filtering.
