Rated 5 out of 5 stars

Love it, and use it as my current TB theme. One suggestion: maybe it's just me and my old, tired eyes, but I'd wish unread messages were highlighted even stronger, since the bold type doesn't help to differentiate them much from read messages (at least to me). Not a deal-breaker, though. :)

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

Thanks for your review :) I m glad you appreciate my work and that you are using it.
Concerning your request, lately already few users asked me the same, so I uploaded a new version (2.0.1.2) with a blue font for the unread messages. Did you install it or you are still running previous version ? In case you still didn t install it, here is the link > https://addons.mozilla.org/fr/thunderbird/addon/bloomind-tt-deepdark/versions/
