Isn't that a job for "noneatall" [0] -- maybe it just needs the
ability to export to static pages, that can be rsync'ed somewhere?

Is that an argument for tags on a thread rather than a message? With a
message mute tag, if you happen to delete the single message you've
tagged muted (maybe you killfile the sender of that message), suddenly
the whole thread reappears, which doesn't sound entirely desirable.

An MUA that did that well (or just effectively) would be massively fantasti=
c.

Perhaps you could do it by associating threads with any message, so if
you've got an announcement A, with three followups, B, C and D, of
which C and D are interesting and novel subthreads, you could have
thread:00001 start at A and include everything, thread:00002 manually
pointed at C and include both its parents (A) and any children, but
not any siblings/cousins (B/D), and thread:00003 manually pointed at D
and behave likewise (including A, any responses to D, but not B, C or
any replies to B or C).

I don't know how you'd handle a mail, E, that came in that following
up to C though -- do you just report thread:00001 as having new mail,
or just thread:00002, or both of them? What if F comes in that
simultaneously replies to E and D? (Personally, I could probably be
comfortable with any of those behaviours)

The above hypothetical features could let you do:

    # create new threads at messages that are marked as postponed or merged

    notmuch newthread -- not is:threadroot \( tag:merged or tag:postponed \=
)

    # assume threads get the same tags as their "root" message, so that
    # any messages in the above new threads will automagically match on
    # threadtag:merged or threadtag:postponed. Thus:

    notmuch search threadtag:merged 123456..123789

That's abusing subthreads as a poor man's set. Not really convinced
that's a good idea, but what the hey... Something to think about
maybe.
