Review for ThreadKey by jarechu
Rated 5 out of 5 stars
If you are a mailing list adict this extension will help you a lot. Before it was imposible to me to have a folder view with the newest first withouth breaking the threaded view. With this one I can see always the newest threads on top, like I am used to in my mail views.
