You have a interface for youtube or local media library (if you use youtubedl) and you can create playlists of videos, and THEN you can watch them and, while watching, add timestamped comments / notes etc (think about comments on soundcloud, only for you only). It would be ideal for self-learning platform - you download some courses for offline watching and you can then create timestamped notes etc per video. Later you can revisits this videos and go trough your own timestamps and reiterate and learn something in your own words and thoughts.
