The improvements have come about following users requests, the company announced. Among the new features is "Volume Control", but the feature has nothing to do with sound. It is a bar that will turn up or down the amount of feed you may get from a circle. If you have a circle with people you don't really know that well or acquaintances, you may want this feed turned down low rather than seeing every post. A circle containing your close friends or family may warrant you keeping the volume bar up on full.
Google+ Photos have seen an upgrade too. A new "lightbox" has been added to allow improved navigation and photo tagging techniques.
Google+ Pages have updates too. Companies or brands using Pages feature can now delegate as many as 50 administrators for a Page. Those administrators or managers will now be kept updated of all the activity taking place within that Page. Google+
has attempted to win customers over from Facebook since its launch in June 2011.
reports the Google+ Bar has seen a small facelift too. They have redesigned the notifications which appear as red icons (on the right-hand side of the Bar). Now it's easier to see what’s happening on your Google+ profile along with all the recent shares you have received.
