In the "computing" screen, one can add new applications.
To add a new application, a template must be used, and the window class for that application must be known. Window class is a property of every X11 application.
The WM_CLASS property (of type STRING without control characters) contains two consecutive null-terminated strings. These specify the Instance and Class names to be used by both the client and the window manager for looking up resources for the application or as identifying information.
