I love it! Rated 5 out of 5 stars

OOch, I just love this add-on; it is so beautiful and easy to set-up and use. I was using Eudora for years and just recently switched to Thunderbird and now, this Walnut add-on . I just love the look and layout. I haven't installed the calendar yet, mind you, but when I do I'll comment about that. I love Mozilla products because now I can SEE what I'm reading and writing. hahha ;))))

This review is for a previous version of the add-on (1.7.18).
