Hi, I'm a student and I'd like to be able to change the color background or border of my courses once I'm inside them. I'm taking four classes right now and have to look at the top of the course to make sure I'm in the correct one. I've changed the colors of my course cards on the dashboard but that's not very helpful once I'm inside the course. Is there some other way I can distinguish one course from another once I'm inside the course? Thanks!
