Addon works nice now for computer with little screens.

Agree with C5's post, Thunderbird interface was enough for me too...

+ Problem on a 1280x800 Debian computer : when opening the book tab, it's pushing Thunderbird over the screen on the right !!! Please don't allow the tab to resize the TB's window on the screen, you can't access the right of the window :/
I hope a update soon.
