A more detailed online list?

I was thinking on the online list it shows guests and ip addresses. Under the IP address, could you have it show if it’s a direct hit or the site that they came from via link? So if they found your forum on Spark Promotion in would show guest, IP, and SparkPromotion.net. Also could each user(member/guest) have a drop down list that shows all of the forum they viewed while they were visiting? So maybe it would just show index but in the drop down list, if they visited 5 different topics, it would show all of the topics the viewed?

I think this would help users see where traffic is coming from and what interests visitors.
