If you log into your adwords account today you may receive a pop-up alerting you that a new ‘Beta Interface’ is available. If you don’t have the notification look to the upper right hand corner for a ‘Beta Interface’ link and it may be there for you..
You can see the interface in the screen shot which looks like a mutation of Google Adwords and Google Analytics. This is a much needed improvement in usability and efficiency. I love the ease in which you can navigate through the campaigns and ad groups, the graph and the expanded view.
