Is there a convenient way to hide lessons/courses from the Library? For some languages, I've studied a decent portion of the lessons in the Library. Now, every time I look for new lessons I see a lot of lessons over and over that I'm not interested in studying, especially certain lessons in the Chinese library that are just vocabulary lists. This makes it hard to find new interesting content. Can I hide a certain lesson/course/provider and restrict browsing and searches to lessons I might be interested in studying in the future?
There isn't really any way to do this, as the Library is a collection of courses and lessons that you haven't yet studied. Perhaps in the future it might be possible, but not in the current implementation. What I might recommend instead is using some of the filters, such as filtering for a specific number of new words, or organizing lessons by date. You can also select a specific provider in the expanded filters.
