I didn't see this new link yesterday but today in the Ad setup pages I notice a link to 'add new channel'. When you click it a popup appears that lets you add a new channel name. This means you don't have to leave the set up pages to go to the channels page to set up a new one which means you don't loose your design etc. I was only thinking yesterday that this was one of the more annoying parts of the AdSense set up workflow - a welcome change. Screen caps of it here.
I actually found it usefull today. I did all my ad codes specs. and then saw select a channel? And was like damnit! I gotta go back, but then underneath it I saw that option.
Me too - in fact, I requested this change on one of their surveys. Nice to see that they're listening. Sam
FYI, it's a JavaScript prompt/input message box not a popup window: var channelName = prompt(channelPrompt, '');
change is the only constant as we hear so often. and this change is soooooo good and definitely enhances the experience
