It's been mentioned, but for some of the courses that I'd like to create, it would be incredibly useful to have levels/chapters the way memrise did. And, if possible, some way to write a descriptive text for each of those levels with explanations, links out to articles on the grammatical concepts, that kind of thing. It's nice to be able to chunk concepts together and know when you've gotten to a stopping point.
Thank you!
Edited to add: Would it be better at this point to go ahead and create them as several smaller mini-courses? Like I'm planning out an A1 Italian course that could have at least, say, fifty discrete levels in it. But I could go ahead and get started on creating these as "My A1 Italian x/50". That might end up really cluttered on people's dashboards, though, and wouldn't combine them all together for reviews.
