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.
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.
The LinCastor enables you to register your own custom URL scheme (e.g. mylink://foo/bar) and associate it with an application, shell, or AppleScript handler. As most OS X application support embedding links as part of a text, custom URL schemes provide a great way to connect different applications together or trigger custom workflows. For example: a link jira://issue1234 could open a JIRA tracker with specific issue. Another use is to associate well knows URL schemes with specific application. For example: firefox-http://www.mysite.net would open http://www.mysite.net in the Firefox instead of the default browser.
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.
