I am indeed using the default. I think you forgot the screen shot.

I think so, although to be honest I never tried imenu before testing
your patches, perhaps we should wait for other opinions.

I guess I don't really understand how the matching is supposed to
work. If the user has to type from the beginning of the index string,
then I guess putting either the date or the subject first might be
helpful.  It's probably true that there is no one good order for all
threads. Some threads change subject often, others author, and one I'm
looking at right now has 25 messages with two authors and one subject.
