Needs work and improvements.

Well… As this plugin only adds a new, empty field yo CF7, it’s not pretty helpful.
I mean… it could be great if the plugin would let me choose from a list which posts atts I want to retrieve, but you have to write the field itself.

So I don’t see the point of this plugin, because if you have the knowledge to code the field to retrieve desired data, you already have the knowledge to custom code your CF7, so you actually don’t need the plugin.
