This looks like what you want.
A couple of weeks ago, the extension Promnesia was on the first page of HN (Haven't used it, but looks interesting)

Its github goes more to the point of what it can do https://github.com/karlicoss/promnesia#readme
Working on something similar for a while now. Soon!

I'd be grateful if you could notify me when you release what you're working on. Email is in profile. Thank you :)
Would be a killer Chrome extension if such an extension can work across domains in this manner. Take my money.
