acpt/settings/capability – Determines capability is needed to manage custom post types.
acpt/settings/save_json – The path to save post types locally.
<h3>Actions</h3>
acpt/init – Fires before acpt has started loading.

This plugin can be used as an add-on to the Advanced Custom Fields Plugin. 
Helps you add a class to any of the ACF Custom Fields, including repeater, flexible content. 
The brush icon corresponds to the ACF CSS ADD-ON feature. You can click on this to add classes for the field. 
Add multiple classes to the fields by seperating them with spaces. 
Add class to options pages also.
<h3>Arbitrary section</h3>
Use get_field_classes(‘fieldname’) for simple fields eg. text, url, password, textarea

Use get_field_classes(‘fieldname’, ‘option’) for simple fields eg. text, url, password, textarea in options page
