Google has revealed new feature in Adsense, which is called Manage Ads. The new feature lets you change ad block options from your Adsense account without touching ad code in your page code. Here is a screen shot: From official Adsense Blog:
I already have it (as i said in my previous post). Don't see any ads now but it says it can take more then 10 minutes before the ads show up.
