It seems as if Google has updated AdWords to add a "settings" link on the keyword level pages. Here is a screen capture of what you may see;
Many of the WebmasterWorld members dislike this new placement of the settings link. Moderator eWhisper said; "Actually, I liked the old style more. The ability to quickly mouse over a few URLs to check the tracking codes was very useful."
Later on in the thread, members also notice that the Traffic Estimator tool has been updated. One member said that the tool does "not give an exact number, but a range of estimates, making the estimator feature even more useless." Cline adds (1) Inability to easily see and sort on destination urls, (2) harder to interpret traffic estimates, and (3) loss of the totals line for the traffic estimates all add up to a worse tool.
He also notes that there is a thread that shows how now reports can only be generated using IE and does not currently work in Firefox.
