Restore the one-click 'auto fill to contact list' when you were reading an email. It was nice that it allowed you to decide if you wanted to add them to you contact list, and then had to 'do a positive action' to make it happen. You had this function in your Classic Mail, but the new mail does not. Now you have to type everything and watch out for typo !!

another reason to totally hate this new contact list - totally agree - classic mail was much better than this new mail and also better than the basic mail, especially for the contacts, I either have one contact missing or four of the same person in my contact list

I agree. Arent new improvements suppose to make things easier? In this case, it makes it harder. I want to be able to add names to my contact with without opening the Contact Icon... just do it in the email.
