Adwords - Functionality Request

I'm constantly looking at sites / application UI's and think how they can be improved.

Today I was in my Adwords account looking at old campaigns and seeing if I should put them back live and whether they need tweaking etc. I came accross the one direct to merchant campaign and starting trying to think why I paused it. Was it because it just didn't provide an adequate return, was it because the merchant had site issues, was it because I wasn't allowed to brand bid, was it because the offer they were running out had ended, was it because the merchant is deactivated???

So I think one feature for adwords I'd like is a "sticky" feature where you could add a note against campaign to make notes about what you've changed and when and why you've changed it's status etc.

I wonder how many other PPC'ers out there would like that feature - and not just with Adwords?
