Google has revealed that they are rolling out user interface enhancements on their AdSense backend.

These new enhancements are aimed at streamlining the design to match their new design guidelines.

Google said:

Your account will still have the same general structure, but you’ll notice some gradual updates to introduce cleaner design elements. If you’re also using Analytics or AdWords, you’ll be familiar with some of the updates. We’ll be gradually introducing these updates to AdSense accounts in the next few days, and we welcome your feedback and suggestions in the meantime.
