Once you have made a question one of your favorites, how do you get back to it? I noticed that when you click "Questions" you go a new page with categories "newest," "faq," "votes, "active," and "unanswered." Shouldn't there be a "favorites" category too? And, wouldn't in be cool to be able to see a list of favorite questions ordered by the number of people for whom they were favorites?
The list of favorite questions would be important for users, Wolfram, indeed all mankind.
