I love the idea that Thunderbird will now mimic exactly what I love about Gmail. But this update in Thunderbird has too "loose" a definition of a conversation. It links emails that are not related except for the fact that they seem to deal with budget issues, even if they have completely unique subjects. And when every email I send regarding payments is considered a single conversation, regardless of subject or recipients, it makes this add-on worthless to me. Sadly, I have removed it.

This review is for a previous version of the add-on (2.0.7). 

This why I've written what is threading: https://github.com/protz/GMail-Conversation-View/wiki/What-is-threading
