In Lion and Mountain Lion Mail, the "Mailbox List" included an entry for flagged messages, with an sub-entry for each kind of flag. This appears to have been removed in Mavericks Mail. Is there a (perhaps hidden) setting to restore this, or is it gone; and if so, how can I get a list of my flagged messages (of each kind).
I've tried creating a "Smart Mailbox", but that doesn't seem to work.
