'Add New Custom Type' screen, where you can create custom post types.
Customizing provides a nice interface for you to create custom post types, taxonomies and fields (meta boxes).
You’ll find the Customizing tools in the ‘Customizing’ menu.
In the ‘Custom Box’ screen, you may show and hide groups of fields, and order them the way you like.
All the settings are based on the WordPress API settings, therefore, the oficial guides apply to them.
