Makes it very easy to see how many e-mails are from a particular sender as well as being able to sort by sender to see who are the frequent senders. Has helped me reduce the number of e-mails in my inbox dramatically. One of my most useful thunderbird add ons.

This review is for a previous version of the add-on (1.0.1).
