Your Idea

Friend's suggestion: On the regular course schedule page after you've searched for a course (say Upper-Div Math Courses), there should be a button that allows you to filter to only non-conflicting courses. That way instead of having to scroll all options and see what isn't crossed out manually, you have all options viewable instantly.
