Could a Legend or Key be displayed somewhere within Commons so that when people do keyword searches (such as "math" shown in this example), they know what type of content has been found? I created a rough mock-up example (didn't know what the "Audio" image looked like because there aren't any results for that category at the moment). Currently, there isn't any indication of what each icon means. I was talking with an instructor this morning, and he didn't understand what those icons meant. I'll admit I only recognized a few of them like "Quizzes", "Assignments", and "Discussions". The ones for "Courses", "Modules", "Documents", etc. were not as clear.
