Developer Full Screen Preview

Hi, Is there a way to easily do a full screen preview of my view in Perspective Developer?

2 Ways to preview the Pages

-There is a play button to see the preview, you can see well the functionality but you don´t see so much the design as it keep the defaultSize 800x800 so is not as seen it on a browser.

-If you launch a session and you leave it open when you save it on Perspective Developer it updates with the new changes (it may take a little while)
