Story Lines is developed by Jacob Martella, a new plugin for an easy way to display highlights of a story inside of posts. It has meta box to the Posts screen which means users can name the highlights box, configure its width, how it’s displayed, and fields for three highlights. In order to display highlights in a post, click the SL button in the visual editor and adds a shortcode to the post. Story Lines don’t have a setting panel to configure its design but if you want to change the design itself, you can check here on how. It is available for free from the WordPress plugin directory.
