It seems like soon Google+ users will be able to get a new Chromecast option to share their photos and videos with their family and friends across devices. Recently few Chromecast Icons have been spotted in the latest Google+ Android APK file which hints that Google is working to include the Chromecast support in this app.
Well, currently there are no official details regarding this feature, but we are expecting that Chromecast in Google+ would work similar to other Chromecast app — hit the button and it will beam your content straight to your TV. But Google is having the option to introduce something new too. So, before getting excited, it will be better for us to wait for the official updates.
