Google recently rolled out a new Google Contacts interface with improved features like merged contacts and automatic duplicates finding. One of the best features is the option is to choose specific Google+ circles to show up in "your circles" and your "all contacts" section. Here's how.
All you have to do is head to this Google+ setting and uncheck the circles you don't want to show up in the "all contacts" section in Google Contacts. That way, when you're browsing for a contact on your phone or computer, it's not cluttered with all of your Google+ contacts.
The downside, Google Operating System notes, is that the "your circles" feature is less useful when using Google+ to share posts with your favorite circles. But you could always manually select additional circles when creating posts, so it's just a matter of weighing your options.
