Google has updated Google+ today with a couple notable and highly requested new features for Hangouts on Air users. The first big new feature is the ability to rewind live broadcasts, allowing users to navigate back to the beginning of a broadcast regardless of when they started watching. Other improvements include higher quality video for those joining Hangouts on Air from a mobile device, as well new auto-playing broadcasts that don’t require users to refresh the page when aHangout starts.
Google did note that “it may take longer to set up your Hangout On Air. For example: the ‘Start broadcasting’ button may be grayed out for a bit, before it turns red.” That change is to provide users with enough time to get everything in place before starting the Hangout.
