As part of our cool visualizer, you get also a schema creator tool that works like a block builder but for GraphQL. Besides being a visual schema builder it also gets some jobs done for you like:
With this feature GraphQL Editor automatically adds interface fields to the type - when the interface is implemented using visual editor. Also when field is added or removed from interface it disappears from all the implementing types.
As you can see the address type which comes from interface is locked. That means we can only modify it inside the original interface type.
