I got a whole bunch, but I'll start with just three:

* Within the interface, the ability to delete keywords, ads, etc. via the search results screen - right now, from the results one must navigate to each keyword, ad, etc. in its respective ad group in order to delete it

* Ability to sort within the Editorial Status tab (by keyword, campaign, ad group, submitted / reviewed date, etc.)

* Within a campaign, the ability to set unique bids for multiple ad groups -- on one screen. Check mark all that you'd like to change, edit 'em all...

Anyone else?
