ActoTracker is an application for keeping track of activities on your desktop so that you don't have to. Think of it as an app for bookmarking desktop documents and applications. It can also bookmark things that are not usually tied to a URL such as Outlook email message or Filemaker records. It can be extended to handle additional applications by writing custom AppleScript plugins. ActoTracker is somewhat inspired by the GNOME Activity Journal (Zeitgeist framework), and it tries to solve a similar kind of problem for the end user, although in a different way.
