The Lingq library is very messy and it would be nice if things could be improved on that front by allowing users to create their own course shelves that would be kept separate from the library. I read books and would like to be able to sort out the novels I read by genre e.g mystery, YA etc. Yes, there are tags, but it's not the same.
Ideally, the user could also move completed courses to a dedicated shelf since you don't want to reintroduce archiving. At the moment, everything is crammed onto the continue studying section, but completed courses have nothing to do here by definition.
