Rated 5 out of 5 stars
I use a ton of folders between my 10+ mail accounts. This is great for switching between my 30+ favorite folders, unread mail and all folders. I hated having to go to view->folders-> and select unread, favorites or all. The arrows on the pane view switcher are perfect. I've give this 10 stars if I could.This review is for a previous version of the add-on (2.0.1).
