Hi there,
This tool has helped me in a couple of projects. So, thank you very much for this great tool!
I have a couple of suggestions that I think would make your tool even better:
In of the solutions I have developed I have used json views so it would be great to have the option of creating views/[viewname]/view.json.php view with just using request &format=json
Moreover, it would be great to have the field type Globally Unique Identifier (GUID)
Regards
