Now that Chrome 37 is released, there is a new API, identity.getProfileUserInfo . I am not quite sure what information is intended to return or what it represents.
From the documentation, I thought that it would return the email address and user ID of the user signed in Chrome (that is, from the hamburger menu), but this is not entirely true - when I call it (from the extension context, which asks for "identity" permission) , I get the user ID signed in this way (and if I insert it after adding it to plus.google.com/, I get their G + page), but the email field is blank. Is this intended?
