I need to create a diagram of an application and the page flows. I'll probably use visio. Has any one done anything similar? or does anyone have a script to query the flows schema and return each page with the branches from it. It would be a lot easier to document if I had a printed list of pages rather then flicking back to htmldb for each page and branch.

While I'm here, is there a way to record the preferences I set regarding number of pages to list and the group selected to always filter unless I change it. It's most annoying to have to refilter and find the page I want each time. Even better would be if I could filter the list of pages based on a selected tab set.
