Well, I haven't thought about it all that much in detail. Or, actually,
I did write a how-to: http://imapwiki.org/ClientImplementation


1) Online mode: Don't download all message headers at once at startup.
If I open a mailbox, I'm seeing only about 20 messages on screen. That's
all it needs to download. When I scroll the message list, download more
as needed.

2) Just implement IMAP protocol correctly and efficiently and without
pointless settings, such as TB's "server supports folders that have
subfolders". The HOWTO is mainly about this.

3) Don't download message attachments when I open the mail.

4) When I actually am downloading a larger attachment or doing some
other long running operation, don't block the UI or anything. Create a
new IMAP connection if needed.

5) And in general the UI shouldn't hang and it shouldn't waste my

There are probably a lot of other things I can't think of right now.
