Still not sure if it’s an “Easter egg” or simply a layout problem, but when viewing the “Apps” category in the Google Play Store app, a special “Chromecast” section seems to be hidden off to the side. It’s only viewable when turning your Android device around in landscape mode, and when clicked, shows you the usual assortment of Chromecast apps compatible with the Chromecast. Also, swiping to the “Categories” section also reveals the button, acting as some kind of weird overflow.
Nothing too huge, just something Chromecasters might wanna keep an eye on for future additions. Something tells me once the SDK goes live, it’ll get a lot more crowded in there.
