Saw this over at 9to5Mac:

If implemented, this feature will be great for me, since I would prefer the Podcasts icon to be next to Netflix. Why else would you want to move icons unless you have a ton of them available? Makes me wonder if Apple is planning something bigger, like native Apple TV apps.

I wrote an article last year discussing how there were already Apple TV apps available via streaming from your iPad or iPhone. While passable as an option, having them baked in would be great. No longer would you require an accessible and fully charged iOS device to run apps on your TV.
