Why can we move the Gimbal UP & Down but not left to right?

  Yes I know we can just roll the AC but it would be nice to just roll the camera. When you are a taking pictures it seems it would be easier to roll camera horizontally.   

I have heard that it is possible with the Goggles? I am still waiting for my Googles to ship July 4th.

Am I missing something or is this just the way it is?  

Think about what you are saying... if you "could" roll the gimbal only, you would end up taking a picture of the drones front legs

Doesn't do it!
