Report to look at Bing data vs Yahoo data.
It would be great to be able to segment performance by Bing vs. Yahoo SEM.
I would love to be able to see a breakout of search performance on Bing and Yahoo since these are 2 distinct search engines. I would also love to be able to allocate a dollar or percent to each search engine.
For what it's worth, I really wish you guys were better at delivering search results and had a better interface for advertisers to give us a viable alternative to Google and to force Google to be better.
