Google announced that starting today you can now view "top 10 performing custom and URL channels directly on the homepage of the new AdSense interface." This latest change will allow you to get a quick snapshot directly from the new interface, said Dan Banfield - AdSense Engineering.
"When you log in to the new AdSense interface, you will see your top channels by estimated earnings along with the percentage change for the selected time period. So if you have chosen to view the last 7 days, you will see your top performing channels for that time range along with the percentage change they experienced compared to the prior 7 day period," explains Dan.
He also reminded, that Google is gradually moving away from the older version of AdSens interface and focusing on building improvements like these in the new interface.
