Just came across a great little app for those of you that have pinged me regarding changing the font size in GoodLink.

Fonts4OS5 version 3.21

This $12 application (14 day free trial) allows you to change the font style and size across all applications or you can have a different font for each application. We have tried on the 600 and the 650 and it works beautifully.
