You can just let gmime cache the headers, it is already doing that. But
don't think about how to implement it, think about what you want to do

You can always name the macro libbalsa_message_get_subject...

The local case is easy, just use lots of memory and cpu :-)
I was thinking about the imap case, you could get a selected set of the
headers with, for example, the FETCH command. So when doing threading you
first fetch all the 'message-id', 'references' and 'in-reply-to' headers,
use that to build a threaded tree, and than fetch only for the messages in
view the 'subject', 'date', etc headers.
So if you want to minimize the bandwidth used for imap you should request
the absolute minimum at the display part. How the mailbox and message part
handles it, is not the consern of the display part, it should just ask the
message/mailbox where you can do a lot of smart things.
Reread my message with the above in mind, I think it will be much clearer.
When a guy says "the last thing I'd wanna do is hurt you" it just means
he's gotta do other things first.
