All the included in our theme plugins are external and we do not have the right to build them into our theme as we purchase the Extended License for each of these plugins. The plugins run perfectly and are fully functional.
Keep in mind, we are constantly including the plugin updated versions and while every theme update you may find the actual plugin version in the theme folder. There is no doubt that you can get the current plugin version directly from us.
These plugins registration is not obligatory! The plugins are functioning perfectly without any activation. The plugin activation option was added in the plugin only for the customers to get automatic updates and support directly from plugin developers. Whenever you need these features you will need to purchase and register the plugin. This is not only our practice but all the theme authors from ThemeForest.
