How to I get my old email "contact" list format back?

Unfortunately for a number of us (probably thousands), the old Yahoo Mail Classic appears to be changing. My "Options" tells me "Pardon us, we are changing things. You will have to go to AT&T mail classic" to return to classic- everything has really changed. The contact lists are sorted by FIRST name only, and do not even list all of the information from the person, just the First Name, then the Last Name, no Nickname, no e-mail address, no phone #. It really stinks ! It will be impossible to navigate around these contact lists and send to the appropriate people, especially if you are picking and choosing multiple contacts.

I also don't like this new format. It is horrible. No option to sort by last name, no nicknames show, and the email address itself doesn't appear on the list. I tried to switch back to Classic, but the format is the same. Anyone else manage to get the old format back??
