CloseReview for Compose for Thunderbird by klint
Rated 5 out of 5 stars
Just opened a new mail, and....WOW!!!
5 stars for the idea and the initiative :)
Haven't tested it yet though (but will have some trouble at the office, as the Contacts addon does not connect to LDAP for the moment, as far as I know)
