So, regardless of what's going on under the hood, there could still be a way to offer the option of setting the "viewpoint," then, based on coordinates, no? In a similar fashion to setting extent in MVC? If the capability is there and modifiable in the JSON, why was the UI for making these modifications removed? It's just baffling to me that we now are told to rely on eyeballing it or knowing JSON when it used to be such a simple task and still could be. The disappearance of this functionality has been a headache.
