collecting recently-viewed messages

[Eric Abrahamsen <eric@ericabrahamsen.net>]

Over the past couple of years I've gotten gnus smoothed out pretty well.
But one continuing annoyance is with recent emails -- throughout the
course of the day I'm often referring back to emails I got in the
morning, forwarding things and replying multiple times, etc. I could use
a persistent nnir search group, except that I use Namazu for search
indexing and I'd have to update the index every hour or so to make it
useful.

I use the registry: would it be possible to use it to populate a virtual
group containing the last 20 registered messages? Are they ordered by
time of entry? I've got 2500 messages in there and the file's one long
line, and it's pretty darn hard to examine with either emacs or command
line tools.

I would love to hear any potential solutions to this, or even gentle
pointers in the right direction. Virtual groups are dragon-infested
territory to me, but I'd give it a shot.

Thanks!
Eric
