Cover Flow now comes in a full-screen flavour. It's pretty sweet, but unfortunately the remote controls iTunes exactly the same so you need a mouse to flick through the covers.
That made me wonder if Front Row used this full-screen Cover Flow view for albums now, but it doesn't. I hope Apple gets on this and adds it to Front Row and the Apple TV. I'm sure it's already on their list.
I would love to be able to flick through my albums with the remote right now, but I'm not going to install one of those 3rd-party remote config tools. Guess I have to wait for Apple to do it.
