Best TB Addon Ever Rated 5 out of 5 stars
This addon is the best TB addon ever, without doubt! If I want to donate some addons someday, this would be first.
Using this addon I can easily track my conversations and realize in response to what email I received/sent this email, without the need to go between Inbox & Sent folders repetitively. It's preferences is also very versatile. For example I don't like its default message body font tweak and I could easily cancel that to original TB font.
Using this addon you can see your threads easily, both in threads pane and in message pane. Plus you can see the thread messages in new tab both as part of the conversation using this addon and separately in the traditional view.
