It adds a few new columns in the message list which is brilliant. Now you can finally have a proper thread display.
But then it messes with the message display window/pane. It uglifies the header view, changes the quick filter button display and what not. I had to uninstall it.

This review is for a previous version of the add-on (2.13.2).
