A feature I would really like is to be able to register your own advanced field type with Gravity Forms.
For example, if I want to add a dropdown menu of countries it is a pain to enter them all manually. Would be much nicer if I could code it and register it as a field type that would appear in the advanced field on the right and I could add to my form.
Or....
For example, if I have a plugin that uses custom post types in WordPress to create a new post type called Properties, and I want my plugin to automatically make a dropdown menu available in Gravity Forms to list the properties. The menu will dynamically list all my properties so if I add a new property post it will automatically be available in the form.
I'm thinking it could be implemented a bit like registering a post type but instead you register_gform_field( 'name', $options ) or something?
