Review for OxyBird2 by Mizu
Rated 5 out of 5 stars
It works, and it looks very good (really integrated look), I like it very much.
milehigh, thanks for the hints, how to install the latest version. I don't know, why they don't update the file here. It's a pity, but I appriciate their work with 5 stars.
It is working in Thunderbird 11 (on Kubuntu 12.04), too, just follow the steps in milehigh's post.
