I have more than two Active Goals, and only two are displayed on the Dashboard. That's typically not a problem, as you have the "See All..." option, which takes you to the Active Goals tab. But what I like about the Dashboard view is it portrays the current day in relation to the goal's period. This gives you a quick assessment of your progress, and shows whether you are on schedule to successfully complete it.
Either allow more Goals to be viewed on the Dashboard in this manner, or provide this progress indicator on the Goals/Active Goals tab.
