If your Mac is ever stolen and Mac Calls Home is installed, it will inform you of its location by using an existing Internet connection. It will try to send as much information as possible about the location, and if an iSight camera is available, it will snap a picture and send it to you as well.
TagoMan enables you to tag your documents, email, Web links or even iCal events and address book entries in a simple and consistent way. This allows you to group relevant pieces of information together regardless of which application it came from or where it has been stored. Furthermore, TagoMan can facilitate tagging as part of your daily workflow by offering full Automator and AppleScript integration. Its use of the OpenMeta framework means it can be used with an ever-growing number of applications out of the box.
Launch is a menu for favorite applications and documents. Installing Launch creates a folder in the home directory called "Aliases". Any number of documents and shortcuts can be placed in there and arranged in a hierarchy of subfolders. At login, Launch scans this directory, and creates a menu in the status area from which these files can be opened instantly. There are no other options or features in the menu; just exactly what is found in "Aliases" at login and no more.
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.
