PedPal provides extensive configuration/customization options. These can be accessed using buttons and settings in the right side panel and with the Preferences and File Settings windows. You can also access many customization options though context popup menus - right-click (Mac: use Control + Click) over any part of the displayed pedigree then select one of the 'Settings' options.
The Preferences window is accessed through the File menu (Mac: use the 'PedPal' application menu). It is used for settings that are independent of any particular data file.
The File Settings window is accessed through the File menu and is used for all settings that can alter the current data file in some way - such as user defined data fields.
