Share Web Pages and Check Google+ Notifications from Anywhere on Chrome [Official Extensions]
Google just rolled out two new Google+ features that integrate with most popular Google products – YouTube and Chrome. On opening Google+, you will notice a YouTube option at the top right which lets you instantly search and play your favorite videos by selecting them from a list of related videos, shown in a new pop-up window. You can also +1 any video or share it with your circles on Google+ in a few clicks.
Google has also released a new Google+ extension “Google+ Notifications” for Chrome that is just a clone of the popular G+ extension Surplus, but is an official one. When signed in, it lets you view notifications of Google+ activity from anywhere on the web on Chrome. The extension icons turns red whenever there is a new unread notification which can be simply viewed by clicking on its button.
You can reply to a comment, +1 a post or comment from within the Google+ Notifications drop-down menu but you cant share a post using it unlike Surplus. Now you can quickly check notifications while browsing the web and without opening Google+.
