Flow looks nice but it doesn't show what I want out of analytics, which is link sources and conversions. What I would like to see is flows like:

CPC ad click -> Product Page (secondary goal: email signup) -> Cart -> (time passes) -> Googled "product" -> Product Page -> (time passes) -> email click -> Product Page -> Cart Page -> Payment (primary goal)

I want to see is where people come from, where they went, and why it works. In the example above, the thing that worked was email reminder. It gets even worse when referers are involved, and blog posts don't remove the utm_campaign=email link.

Basically, I'd like a backwards flow from individual conversions.
