Even after you do this, you'll notice a few strange labels in your Gmail account: [Imap]/Sent, [Imap]/Drafts and [Imap]/Trash. These are Thunderbird's default Sent, Drafts, and Trash folders. Once you make the change to your account settings, you can delete those labels in Gmail and they won't get regenerated. (Note: except for [Imap]/Trash, which I can't rid myself of entirely, since T-bird seems married to it. Bueller? Update: see the next section for the solution to the [Imap]/Trash label.)
Threaded conversation view. Ok, so it's not quite as nice as Gmail's web-based implementation, but you can view messages by thread. Click on the tiny "display message threads" button to see replies in a hierarchical order in Thunderbird. Image by
