All the plugins included in our theme are external, and we do not have the right to build them into our theme so we purchased the Extended License for each of these plugins. These 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. Only in case you need this features you will need to purchase and register the plugin. This is not only our practice but all the theme authors from ThemeForest.
