Yes! Rated 5 out of 5 stars

Perhaps this is premature, but I'm VERY impressed by this program!
Excellent layout,very user friendly, etc.....
I've had Thunderbird on my computer for several years now, but rarely used it.Since I figured out how to integrate my other email addresses into this one central program I've made it my default.
Recently I had to learn how to use MS Office on my own,while at work.That was a pain!
This Thunderbird add-on is so cool!

This review is for a previous version of the add-on (0.7).
