Decent Implementation.... Rated 2 out of 5 stars

...of the Gmail type threaded-conversations, if you like that. However, on installing, I was told by the system that I had to delete the global-messages-db.sqlite file twice because I had 'too many messages' to cope with. It broke Thunderbrowse which made doing things internal to Thunderbird more difficult when dealing with certain Internet-activity-centric emails. There wasn't any apparent option to include a 'Reply' or 'Actions' button on the top of the conversation, so you had to scroll down to the bottom of potentially long messages with longer sigs to find them. Uninstalled, and now Thunderbrowse still doesn't work, and attachments are no longer shown 'in line' as they were defaulted prior to this. I recommend it only for folk that are just starting out with their connection, and have limited need for 'other' functions in TB.

This review is for a previous version of the add-on (2.0.8).
