How can I get the old Yahoo Contacts page back. The one that allows you to assign a contact to a list or edit it.

The page used to show the lists on the left hand side and the contacts on the right of it. By clicking on a contact it would show the detail of what lists the contact had been assigned to. It also allowed the contact to be edited and a shortcut name to be added. Clicking on an item in the list showed all contacts that belonged to that list and the number that were in that list. The page suddenly disappeared about a week ago and was replaced by a very difficult page that, in my limited knowledge of computers, is almost unmanageable.
