The new itunes 8.1 added the autofill feature, but I don't want to use it, how do I hide the autofill region of the itunes window? It's eating up a bunch of space so that I can see a few less songs on each screen, it clutters up the interface, and I'm afraid I might accidentally click the autofill button and that would seriously piss me off. How do I hide the autofill view region in itunes?
