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 is updating, 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. For that, it will be enough to contact us via contact form on ThemeForest or our email( email@example.com ) or create the topic at our Ticket System ( http://inwave.ticksy.com/ ) and we will send you the necessary zip file ASAP.
These plugins registration is not obligatory! The plugins are functioning perfect 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 these features you will need to purchase and register the plugin. This is not only our practice but all the theme authors from ThemeForest.
