AWA I want to add my compliments on the new UI features, BUT scrolling keywords and page loading is VERY slow. I am using Chrome .39 (the latest iteration as of 8/8/09) and Java 6 update 15, (the latest as of 8/8/09). I too have the left right scrolling issues, and I am using a 900 by 1440 screen.
How about a "add negative keywords" button at the TOP of the keywords pages, and adding back in the ability to know whether we have already added a neg keyword, when we try to add it in again . . I have 1500 or more neg keywords so scrolling is not an easy possibility in the new UI
