The Yahoo Search Marketing Blog announced new features they added to the Panama (Yahoo Search Marketing) advertisers console.
The largest feature is a method of moving or copying keywords from one ad group to another ad group.
On the Ad Group page under your Campaigns tab, you’ll now see “Move” and “Copy” buttons. As the names imply, these let you move your keywords from one ad group to another and copy them as appropriate. Note that you’re still limited to 100 keywords per ad group.
Select a keyword you want to move by clicking the check box next to it. The first time you hit the “Move” button you’ll get a pop up that shows some useful instructional text. You may opt not to view this in future. You’ll then be taken through an easy step-by-step process for moving your keyword.
Now new advertisers can use the keyword selection tool during the online enrollment process. In addition, they made the keyword section tool easier to use and more useful. Plus, Yahoo now helps you write your ads by giving you ad text ideas.
Those are the new features, the forums don't have much feedback on them, as of yet.
