During stack collapse, a subsidiary program called Stackspy records diagnostic information, logging the location and details of the error. Stackspy is claimed to have no effect on the application's performance. You can customise many of Foundation's features. You can change the contents of any dialog box, and offer the end-user different options on encountering an error. As well as the traditional 'retry' and 'cancel' options, error dialogs can include any of your own custom designed actions.
Brave developers can even allow end-users to enter their own comments when they encounter errors.
