Close to being so good it should be shipped with TB Rated 5 out of 5 stars

This extension shows an odd problem in the traditional UI design of Thunderbird: Namely, that it could be vastly improved.

Thunderbird Conversations has good selection of typical tweaks (displaying attachments, youtube embeds inline, hiding quoted email garbage) and packs the conversation window with exactly what is necessary without compromising screen space.

It almost integrates well with EnigMail, with the exception of the inline composition view -- and that's my only wish atm: Make a setting to disable the inline reply compose view.
