Is there any way to customise sorting of directories in the index?

Ah, oops, I've just discovered the sort_browser setting which
addresses this issue to some extent.  However some explanation of the
settings might be useful:-

    count - does this mean the count of messages in the directory,
    what about if it contains further subdirectories?

    date - date of what?  If it's just the date of the directory it's
    not terribly useful!  

    size - does it work or mean anything with maildir?

    unread - what does this mean?
