Love it! - Keep updating it or I will be lost! Rated 5 out of 5 stars
Thanks for the ONLY vertical tree-tab that works flawlessly and does exactly what it is intended to do. I am surprised no one else has made something similar that actually works like this one. Please keep updating it, time for a donation! :)This review is for a previous version of the add-on (0.14.2014020901.1-signed).
