* is able to search through thousands of emails on the server without downloading the full message contents instantly. Can the MAPI plugin be made to do this too?
* is able to download thousands of message headers and show them in the inbox or a subfolder instantly. I don't know how much overhead is associated with the extra frames sent with the mail vs. the webmail http display but, it would be nice if MAPI could do this as easily as Webmail can. It takes me up to 10 minutes to download about 3k message headers using the MAPI plugin and about 5 seconds on Webmail.
