Transparent Rated 5 out of 5 stars

So simple I thought it wasn't even there!

It has been a constant irritation that new messages with the same subject header get lost yards up Thunderbird's message list, when sorted by "threaded" in view/sorted by.

This little add-on ensures you see new additions with old subject headers.

Well done!

This review is for a previous version of the add-on (0.6).
