Love Noia 2.0 Extreme Rated 5 out of 5 stars

I find it's the best for me -- and it works in TB 16.0.2:

Download Version 3.42 (with standard XT included) from:
http://thunderbird-noia2.pagesperso-orange.fr/page2.html

In TB:
Tools > Add Ons > Appearance
Click the little "gear" icon in the upper bar near the search box
Select "Install Add-On from File"

And there you go. :)

This review is for a previous version of the add-on (3.42).
