Now, you can see Gmail’s Contact Manager has started including the information form Google Profiles. At the same time, you can also find your Google+ circles on the sidebar. The data obtained from Google Profiles will be displayed below the information you’ve entered. Though it is a default action, you can combine them by following the following steps. Open the contact page, click the “More” dropdown and select “[Show external data] inline”.
Moreover, you can see the latest feature at google.com/contacts, which has recently switched to the new Google Contacts interface. You can also find them in the older interface of Gmail.
