[MlMt] Creating a new IMAP mailbox from the keyboard

[Matt Gray]

Hello, MailMate n00b here—

Is there an efficient, keyboard-only way to create a new IMAP mailbox 
within an existing source? I use mailboxes to organize and file my 
messages, and often need to create new ones on the fly. Selecting a 
source with the mouse, using the “Mailbox” menu, and then typing the 
new mailbox name at the bottom of a long list of mailboxes is cumbersome 
and takes me out of the context I was in. (“What was the name

As an ex-Thunderbird user, I used the Nostalgy extension [1] which 
supports a find-as-you-type message move feature similar to MailMate. 
Nostalgy, however, would let you autocomplete a mailbox, then _add a new 
submailbox name_, and complete the move. It opens a dialog that confirms 
you want to create the new mailbox. On confirmation, it creates the new 
mailbox and completes the message move.

I have not contemplated a switch to tags and smart mailboxes as I have 
two GMail-based accounts and many hundreds of historical IMAP 
mailbox-based archives.

I’m open to workflow alternatives / suggestions as well. Thank you in 
advance.
