This idea has been merged into another idea. To comment or vote on this idea, please visit LMS-I-2233 Catalog Category thumbnails to include folder tiles rather than list in card view.
It would be great to be able to add images to categories and see them as thumbnails in the learner side. What it looks like now is equivalent to the detail view in file explorer.
I think this is a great idea; they'd look similar to the tiles then and would encourage engagement/clicks.
This would be a very good addition. Please implement!
