{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"idea of a feature: mark a lesson as \"studied\"","articleBody":"Since you already sell EPUBs, I'd like to propose a paid feature.\r\n\r\nBackground:\r\nBecause this book is so good, I really want to read it from start to finish, and I believe many people feel the same. However in reality, that never happens, because I can never find such a big chunk of time. What typically happens is when I need to learn something, I come to read on that specific thing.\r\n\r\nProposal:\r\nAs a signed-in user, I wish to be able to mark a lesson as \"studied\" or \"have read\", which serves two purposes: 1. it's a motivation for me to read all the lessons and \"check them all off\" 2. help me organize which lessons have been read, especially when I jump to different topics without following any orders.\r\n\r\nIt could be implemented in multiple ways, for example:\r\n- add a button for user to \"mark this lesson as read\"\r\n- mark a lesson as read when user clicks \"next lesson\"\r\n- mark a lesson as read when user's browser tab has focused on this tab for more than x minutes\r\n\r\nThese behaviors could also be configurable as user preference.\r\n\r\nDepending on the implementation, a lesson could even be read multiple times, for example, a ✔ is shown on the page to indicate it's been read, and ✔✔✔ shows if it's been read for 3 times. Clicking or hovering the symbol could show the date it happened, and the duration of the session, etc.","author":{"url":"https://github.com/ZYinMD","@type":"Person","name":"ZYinMD"},"datePublished":"2020-05-18T02:50:14.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":21},"url":"https://github.com/1913/en.javascript.info/issues/1913"}
