Rated 5 out of 5 stars

Absolutely perfect! Good job!
Now my gmail looks nice in thunderbird

EDIT:
Could you please make a option to move folders up or down?
I would like to have my Junk folder from gmail over the archiv.
Example:

now:
> Gmail
Inbox
Send
Trash
Archiv
Junk

I would like to have it like this:
> Gmail
Inbox
Send
Junk
Archiv
Trash
