FeatureRequest: full screen view at snapshot

It would be nice if we can just tap on the camera at homescreen
to have a full screen view of the last snapshot taken. Most of the time we just want the view a photo in large(full screen) to see if it is worth opening camera view (which takes long time to connect and load, right).

If we can see full screen and perhaps even zoom in the photo, most of the time it is enough to decide if we need to take action, eg just ignore the annoying door sellers, or open the door for welcomed visitors.
