As if Android apps hitting Google's Chrome OS wasn't enough excitement for Mountain View's operating system for one week. Now, you can play movies stored in Google Drive via the OS' video player app on your Chromecast. According to Googler François Beaufort, doing so is pretty easy too: simply open the Files app, select a video clip from Drive and hit the sparkly new Cast icon. Voila, cloud-stored videos are now viewable on the biggest screen in your house and even more media functionality for your Chromebook. Of course, since this is in the developer channel there might be a few bugs here and there -- if you spot 'em be sure to let the Chromium team know.
