When building funnels, we could do a whole lot more if we were able to use custom values in the "Custom CSS" area, and the "Custom HTML/Javascript". As a brief example, we could check to see if they purchased a specific product and show different text blocks on the page than if they didn't. Or, we could use Javascript to calculate how many days they've bene a customer, or we could use a custom value to globally change a color on EVERY website in SECONDS. So much flexibility, with such a small update!
