I use a Harmony remote to control all of my AV setups. It's a one-stop remote to control all of your AV devices and includes time saving "activity" buttons.
I've been noticing that occasionally, when I choose to watch something using an Apple TV 2, it will display a wiggling podcast (or other) icon. The same kind of wiggling you get on an iPhone or an iPad when you select an app. This grabbed my attention, and by the time I could find a camera, the screensaver had kicked in, and I couldn't reproduce it. Well I finally figured out how to regularly get the AppleTV into this mode, and when I did, I also found that I could reorganize the icons just like you can organize apps on iOS. All of this is done just using the Harmony remote which is key in getting the AppleTV 2 into this mode as it's only when a specific set of IR commands are issued to the other devices in my AV setup.
So, is this behavior intentionally included for future use(s)? Does everyone know about this but me? Or is this simply an oversight and this iOS code was never intended to be executed without a touch screen?
