Request: Center Image - Depending on browser size

Excellent Human Factors Brain-Friendly design of Photoshop (Beta) WebApp!

Thank you to the team at Adobe that designed and implemented this web version of Photoshop. It's therapeutic and fun-factors to usage are well designed, usage flow analyzed, and coded. I am pleased greatly that I see popups concerning expanding the features. One very minor possible modification would be an additional menu comand from the drop-down, to better center the image on the backdrop area, depending on browser sizing. Thanks very much again, and I appreciate your reading this. -- Patrick
