Possibility to edit or export configuration?

@artfulrobot , further to our lovely discussion during the last sprint about issue #7 (closed) , we did discuss about the possibility to be able to view the JSON configuration easily through the configuration page.

The thing is that the current JSON Editor/viewer that I use doesn't allow you to view the source code that easy, which means it'll be more complex to reach this editor to that point.

What is the main purpose of that request? Is it to be able to export the JSON data as-is so that you can reuse your custom code on another site or is it to be able to do in-place customizations instantly?
