Yo Skool team! Many of us here have multiple courses that could fit within a category, and it looks messy when you have 10+ courses on the classroom section. Having a Course Category/Collection feature would be extremely beneficial, as it would allow for better organization and a clean look. Essentially, you would be able to have Categories/Collections on the classroom section, and when clicking on a Category/Collection, it would then open up a selection of courses the user chose for that category. Just a suggestion :)
