The iOS 6 Beta 2 brings icon reorder to the Apple Tv icons! This was first reported by MacRumors, the report states that the folks over at MacMagazine.com.br noticed the new feature in the iOS 6 Beta 2.
The icon reorder is provoked by holding down the Center Select Button on Apple TV’s Remote for several seconds, after which the selected icon begins to wiggle just like on the iPad or iPhone. The wiggling icon can be moved by using the up-down and left-right buttons on the remote. As the icon moves to the new position the other icons adjust automatically to accommodate the moving icon.
This is a feature many have been waiting for on the AppleTV, as it enables users to get to their most used icons faster.
