I love it

I like to add diced chicken to mine. The brood like to have cut up hot dogs or meatballs (plain meatballs, no sauce) added to theirs. I've never heard of using breadcrumbs on top, it might dry it out a little. Usually I made my own with elbow macaroni and American cheese with a little milk added so it's nice an creamy.

I have never tried bread crumbs on mac and cheese. But that does sound good. Mac and cheese is great any way. As long as it's cheesy.

I add bread crumbs to mine and I love it gives it a good taste

I actually add broccoli to my mac and cheese. I steam the broccoli separately, and then add the broccoli (not the water that it was steamed in) once I've added the cheese to my pasta. It adds your needed veggies and tastes great, too!
