I left this out for simplicity. What would you use this list of watched movies for?Champwq10 commented
That can be a good idea. You can differentiate between the watched and selected. Recently, I read about Andy Yeatman and his shows on http://kidscreen.com/2017/04/04/kids-tv-and-the-power-of-serialized-storytelling/ and realized that these shows have so much to teach and are also very entertaining. So, I added those shows to my collection.
