The template uses several powerful addons to enhance its functionalities and look. All of them are from the default SP Page Builder Pro package except one that is the Timeline Slider. Other than that, all the addons have got a different design to meet the template style. But PHP code for the addons is exactly the same. Only one addon "Timeline Slider" was designed especially for this template in "About" page. The path for the addons is: templates\konstra\sppagebuilder\addons\timelineslider
