CloseReview for ThreadVis by Thom\\'s
Rated 4 out of 5 stars
Great and innovative add-on! This should be standard in future Thunderbird versions. It only receives four stars, though, because it is still a bit buggy.
This review is for a previous version of the add-on (1.0.510).To create your own collections, you must have a Mozilla Add-ons account.
