After the UI change for the Google Maps, now Google is redesigning Gmail experience for Desktop, Android, iOS.
This new design will help to sort the mail as into many categories for better usage experience. The new designed Gmail have categories like social, promotions, updates, etc… If we are receiving a lot of Google plus, Facebook and other promotional offer mails from retailers and it is messing up with our important mails. This new design will be a boon for us.
