Rated 5 out of 5 stars

It's not the extension I was expecting but it's the one I needed. I had something else in mind for a threaded view extension and this is a different approach but it works nicely. It's well designed and easy to use. I didn't quite get the concept until I got a few replies and then it became very intuitive.

This review is for a previous version of the add-on (2.2.0).
