So you just bought a shiny new Chromecast 2.0 for $35. Now what? Google is trying to help folks do more with their purchase with the new Chromecast App. The idea is to help you discover new content so that you have more to cast than just your desktop and YouTube videos. Under "What's On," you can see what's trending on the Play Store, YouTube and apps you may have on your Android device, like Netflix or Showtime. If you're looking for a specific show, say, The X-Files, you can use the search feature to find out which of your streaming apps have it.
