The Preferences tab opens on the ‘General’ sub-tab which is the first of six sub-tabs on the Preferences tab. The ‘System’, ‘Package’, ‘Class’ and ‘Method’ sub-tabs allow the metrics available at each of the System, Package, Class and Method levels to be configured. The ‘Import/Export’ sub-tab allows preferences to be exported as a file that you can subsequently be imported in this tab or from the Welcome tab.
