I would be nice to be able to easily see what apps have been updated to work on the appleTV. Does this exist? Thanks.
I don't know of an easy way to keep tabs on that, except to go into the App Store, and then to your Purchased section so see if the number of apps has gone up at all. There's also SlideToPlay, which has a running list of all new Apple TV apps. It doesn't seem to update very regularly, but it does update eventually. Those are the best two ways I keep tabs on things.
Found a new site, the link is for the swedish store but you can change that on the site https://www.appannie.com/apps/appletv/top/sweden/overall/
