Request "Preview Product Page" in products (admin panel)

Wouldn't it be very nice to have a feature like "PREVIEW PRODUCT PAGE" when editing products in the admin? If I had the programming skills I would do it instantly. I was thinking:
(SAVE) (PREVIEW) (CANCEL)
The preview button should work even when the product is disabled, meaning you could edit your data and try out the options etc without having the product "live in the shop". I dont know what would be best, a pop up window or...

What say you?
