I was thinking about something that each time you click a link, it effects a variable. for example, if went to page 2, %VAR will go down 1. If you go then go to page 3, %VAR will go down one again, automatically. To do this you would have to have it as a setting for creating and editing variables, and there be some sort of way to pause the variable for a link if needed. This idea could use some changing, but I think it would be useful.
