Illuminate allows you to specify applications that you don’t want to show up in Illuminate. These excluded applications are declared in the Advanced preferences.
Basic Use:
In the Preferences window, select the Advanced tab. It contains a list of all the currently excluded applications.
To add an application to the excluded list, type the name of the application in the text field and press return, or press the Plus button. The application name will appear in the excluded application list.
To remove an application from the excluded list, select it and press the Minus button. It will disappear from the excluded application list.
