Add the ability to see search terms that triggered products to show (like Adwords) and make it easy to add those to negative keyword lists. Currently I have to use Google Analytics to figure out the search phrases that were used for bing specific landing URLs in my system.

Actually, you can do this, but it's in the Dimensions tab. It just doesn't allow you to easily add negatives - there's a couple User Voices requesting the ability to make it easier - jump on those and vote for them!
