"home" tab. How to hide closed potentials?

Firstly, great product, thank you!

My question is: 

Is there a way to hide the 'closed' potentials on the 'home' page? I have the dashboards all laid out great, but now realize closed deals take up the entire potentials window. Which makes the that particular dash useless now...

Thanks!
