Decent Rated 4 out of 5 stars

I like this simple design and the colours do work however there's a couple of niggles;

More emphasis on the current tab or less on the unfocused tabs could add some ease of use.

The bottom border of the scrollbar is missing in version 3.5.4 that I'm using.

Otherwise good stuff

This review is for a previous version of the add-on (1.6).
