Mutt could be a lot more asynchronous though. Mutt could display a page-ful of messages, filling in slots (re-drawing as necessary) as the FETCH responses come in. Right now mutt wants to enumerate a mailbox when opening it. It has to for mbox/mh/maildir folders, given their nature. But IMAP is designed to allow for listing page-fuls of messages at a time instead of enumerating folders -- the fact that mutt doesn't do this has me sad. IMAP is also designed to allow multiple concurrent requests, that is, it's designed to allow for asynchronous operation. I've looked at mutt source code, and ISTM that it'd require massive surgery to add support for using IMAP this way. Nico --
