Need default setting Rated 3 out of 5 stars

Zoom Button does exactly what it is supposed to do, quite well. But I could already do that by holding CTRL and rolling the mouse scroll wheel. The problem is that I have to do this every time I start Thunderbird since I am using a 1080p TV as a monitor. TB comes up only using about a third of the screen. And since I use a Kensington ball instead of a mouse it is more difficult. The Kensington ball is great, It's scroll is not so great. PLEASE add a default zoom setting so that folks with HD screens can be happy and give Zoom Button five stars.

This review is for a previous version of the add-on (0.0.6).
