You can get the old version back by clicking on the "SWITCH TO BASIC MAIL WITH FEWER FEATURES" below the YAHOO POP-UP AD BOX. UNFORTUNATELY THIS YAHOO AD BOX CONTINUES TO POP-UP whenever I TRY TO OPEN AN EMAIL. I can find no way to delete this MOST ANNOYING YAHOO AD BOX. YAHOO HELP IS NO HELP as they IGNORE my requests.

No longer possible. Tolerate the new version or use a different service. Many of us are in the same situation.

Yahoo MailSorting my email-it was so simple when they had the icons directly next to the sender. You could quickly put mail in a folder or delete it.
Now you have to go to above section drop down the folder you want and THEN HIT APPLY. Yes deleting is not as bad - it is up on the top also but AGAIN there was that little garbage can that you could just chuck ALL of the unwanted emails. THIS CHANGE IS A PAIN!
