Are you search marketer that uses the AdWords Editor of AdCenter Desktop? If so, rumor has it (via Kerstin Baker Ash) that the Yahoo! Search Marketing team will soon (very soon) officially launch the Yahoo! Search Marketing Desktop.

The application (which apparently runs on Adobe Air) has much the same functionality as its Google and Microsoft counterparts. Features include bulk editing, a keyword tool, the ability to manage bid changes directly in the interface and of course, to work offline.

No official word yet from Yahoo! but we'll keep readers posted on the details as announcements happen.
