Google Plus has finally received an update that lets you decide which circle is more important. You can now use a slider to change the importance of different circles.
Google would push updates to the primary stream based on these settings.
Sometimes important posts you wouldn’t want to miss from close friends or family can get lost amongst posts from others who post dozens of times a day. We’re adding fine-grained controls that will enable you to “graphic-equalize” and fine-tune your stream. When viewing the stream for a particular circle, you’ll now see a slider at the top that lets you adjust how posts from that circle should be blended into the main stream. That way you’ll never miss a post from that special someone, and you can tweak these settings to form your own “perfect stream.”
