Review for Tiger Mail by lordmorgul
Rated 3 out of 5 stars
This theme does partly work in TB 2.0+, all you need to do is install Mr. Tech Toolkit (an extension) and then set the theme to compatible, and TB will allow you to use the theme. I notice no major problems with using the interface, but YMMV of course; I use only mail and do not have lightening or many other extensions installed.
