Can you create a breadcrumb trail for recently-visited topics?

We're trying to move to RoboHelp, but there's a point of resistance. Our current in-house help has a custom wrapper that displays a popup with recently-visited topics. A lot of people consider this a big value-add. So much that there is some willingness for forgo a lot of nifty features in the RoboHelp skins just to keep the recent topics window. Is there any way to hook in a popup window that could track recent topics?

Thanks!
