One of the best Rated 5 out of 5 stars
This is one of the best themes going for Thunderbird. It's clear the designer put a lot of thought and work into it. Usually after I've installed a theme I still tweak quite a bit to get the desired effect but with this one there's virtually nothing I would change. If the reviews are any guide, Walnut2 seems to be attracting more attention these days but this one's still my favorite.This review is for a previous version of the add-on (1.8.56).
