Just as the recent new Google Calendar UI. There is now also a new UI for Googles contact management.
To switch and use this new UI follow these steps:
Open Gmail in a browser. Select “contacts” from the top left selector (will read “Mail” by default). Then go to the very bottom of in the left hand column and select “Try Contacts Preview”.
Contacts will now be a new, freestanding app and no longer a component of the mail app.
No real new features, just a cleaner interface.
