• Standardized API for featuring items

• Register your type

elgg_register_plugin_hook_handler('feature', 'object:my_type', 'Elgg\Values::getTrue');

• Manage permissions

By default, only admins can feature/unfeature items. If you need to change that behaviour, use 'permissions_check:feature',$entity_type hook.

• Notifications/River items

If you need to notify the owner, or create a river item, listen to 'featured',$entity_type and 'unfeatured',$entity_type events.
