Well, now that I've gotten the sidebar patch working, I'm sorry to say I don't see much point to it. It does allow me to get to other mailboxes quickly, but so does 'c TAB' and then j and k to move around the list. In general, the sidebar just seems to take up some screen space and add visual clutter.
Am I missing something? Is it more useful for non-IMAP use? Sorry if I'm stepping on anyone's toes. Thanks, -pd
