Rated 4 out of 5 stars

Most black themes for thunderbird look weird. This one isn't. Colors are balanced, and even though in black there isn't much to see, in this particular add-on the greys and blues seem to match all together to a spectacular art result. Congratulations!
The only disadvantage is that after so many user requests to support new versions of thunderbird new versions just seem to delay.

This review is for a previous version of the add-on (2.0.1.2). 

Thank you very much for this nice review of my work! :) I m glad you appreciate it. There is just one thing I find a bit misplaced, it s the fact that you are criticizing the fact that it has not been updated til now. You have to remember that in lots of cases, addons developers are doing that job for free beside all what they already have to do. I need first to concentrate on other jobs and also to have a private life, before I can work on themes. I would love I could work more on my addons, but for the moment I can t afford that. So even if lots of users are asking me to update for TB12 that doesn t mean that it will help me in having more free time to work on it.
Thanks again for the review and for understanding
