If you later develop a folders-like solution to organise the courses (see Allow Grouping Courses into Collections - #7 by alainravet1 )
It would be super useful to let us store notebooks the same way.
This would allow us, f.ex., to collect 5 articles/lessons around a subject, collect their yellow words and write down notes just about that subject/these 5 lessons, and keep them visually together, easy to access and maintain. (See screenshot below)
