Rated 5 out of 5 stars

Suddenly finding all my sent mail listed in my unified inbox was a bit of a shock as I use it to unify several e-mail accounts and I send a lot of information messages that require no response. After I found out how to turn that feature off (the key step of expanding the folder trees is missing from the FAQ instructions and not immediately obvious from the 'select fold(s)' user interface) I found the add-in worked well and was really useful for following threads. Best to check compatibility with other add-ons you use before installing.

This review is for a previous version of the add-on (2.1.1).
