I can’t organize my contacts effectively since it changed to "People".

All I get is a place to put "name" and "company" when I add a new person.  There is no easy place to see to add an email address, let alone any other information.  I can easily add a new group but it's not clear how to effectively put new people in a newly created group.  Also, I used to be able to just have people in a group not cluttering my individual contact list and that doesn't appear to be the same.  I have a Mac if that makes a difference.  I HATE this "new improvement".

I've also checked out the string "What's New, What's Different" and it's not helpful.  It doesn't address my problem fully and I cannot understand WHY the create new person is so blasted limited.  What good does that do anyone?
