Short lesson description and preview in course curriculum

Hi, 1) Can you add the possibility to add a short description for the lesson in the course curriculum, like udemy ( sorry that everybody want to copy udemy): https://www.udemy.com/drive-traffic-to-your-website-with-zero-seo-knowledge/ There are blue links which open a short description of the lesson. 2) Can you add a video preview in lightbox ( see the udemy link above) They're great features to know lesson content and increase sales. Thanks a lot.
