Whoa! Mail.app can import mailboxes now?


Unofficial Mac Genius
Forgive me if I'm wrong, but I was under the impression that the previous version of Mail (with 10.0.4) had to use those Mail Import Scripts (AppleScript programs) that Apple provided on the web to import mailboxes, but it can now do it natively without needing those extra scripts.

Is this something that I've just been totally oblivious of, or was it really added in the 10.1 version? And if it WAS there before, what did those scripts do, then?
