Contacts — Why has this been changed??

I am so frustrated with the new list of Contacts and how it is set up.  I used to be able to go in and add/change, etc. with no trouble, but now I am unable to create a new list (group) which I need for a mailing list.  I deleted it by accident, as I clicked on the little icon, thinking it would give me a warning, but in a second all my contacts in that group were gone.  Now, I want to recreate it, and cannot figure out how to do it.  Why was this system changed??  It was so simple before.  I am considering cancelling my account, as this is not acceptable.  Phew!  Can anyone help me??  I am not that computer literate, but certainly had no problems with it before.  Very frustrating.
