It's not hard to find a media app with some type of favorites system. It's tougher to find one that lets us be very specific on just what a favorite can be. The new aTV Flash (black) 2.1 update, however, will let Apple TV modders be as exacting as they'd like: they can favorite individual videos, whole seasons and even broader search terms. Catch-up viewers get their own treat in the form of TV show playlists that simplify watching episodes back-to-back. A slew of further tweaks are inside, including iOS 6 support, so there's every incentive to upgrade for those who rely on not-quite-official firmware for Apple's living room hub.
