Because the curriculum rules supersede all course rules, I would like the category description to be visible within the catalog. Then, I can avoid using a curriculum, and I can use the description to let people know how many credits they need from each category of classes.
For a different use case, I'd suggest a checkbox to make this optional. I'd like to give an overview of what the category contains, as some titles are not fully obvious to users. I'd imagine not all Absorb customers want to use it that way, so a checkbox to make visible to learners on each category would be super helpful. It could appear then on the Catalog page as a subhead under each category name.
