Hi folks,

Rafa released slmenu, a dmenu-clone that runs on the commandline, and I
contributed a couple of patches (verticality and tokens) to make it work
nice with notmuch.  So far, I'm pretty happy.  To get slmenu:

hg clone http://hg.suckless.org/slmenu

You'll need to apply the patch at the bottom of this e-mail[1].
You'll also want to use the shell script (nmsl) at the bottom of this e-mail[2].

How it works:

Basically, it pipes output (after being mangled a bit) from notmuch search
into slmenu/dmenu (so you can select the thread) and then sends that output 
to mutt, either via mbox (if notmuch is hosted remote) or maildir (if local).
It also allows you to prepend an entry with v (tag viewed), t +tag (tag
tag), x (tag x-del).

All this will be at:

http://durandus.trilidun.org/durandus/code/notmuch-slmenu/
Best,
Peter
