- Thunderbird themes and skins

Thunderbird Artux 3 panes

A bit like Gmail/Outlook look&feel, based on chrissi4u's 'CLEAN ADAPTION no1' designed for vertical message view. Note that you will have to adjust the width of the panes for the message list to display correctly. You can also modify the subject column (eg. using the Stylish extension). Not guaranteed to work with every window manager.

TB - TwisterMc's "Make TB labels stand out"
