Full page configs to allow better user experiences

Currently, the App config page utilizes less than 25% of the entire real-estate avaialble in the App configuration page.

This restriction forces app developers to create user experiences that are limited to a small frame.

So, we end up having to create multiple tabs inside the space provided.

Instead, if the configs page could be a full-page iframe, it would allow us create apps with better User Experiences.
Like so.
