AdWords makes a great addition to the Display Network tab to summarize the activity and performance of the Display Network. I think this is very new because I am just seeing it in a few Client accounts today.
Each of the metrics across the top of this summary can be clicked on to see a charts of the respective metric.
Also included below the chart example above is a deeper level of data for Display Keywords, Interests & Remarketing and Demographics. These sections all have a drop down that will show the legend info for a different view and a link to full reports for the given data chart.
Here is an example of what the charts look like updated with CTR data.
Sleek design and a great addition in my opinion.
