I understand that we are no longer allowed to categorize or sort email addresses in our address book anymore... Please return that feature.
Without the sorting feature (being able to categorize or sort addresses in the contacts portion of Yahoo), my contacts list is a BIG MESS. Please return the ability to assign emails to categories. This is making us work much harder than before, which is NOT an "upgrade."

Thought about for so long, why no action. This is a fundamental need to manage lists.
