In the menu, when Info->Preferences... and Info->Help... are pressed, no action is taken. It would appear that this is because there are no preferences to be set, nor any documentation for the help menu. To avoid confusion, these items should be removed. To do this, the following lines should be removed from main.m

   [menu addItemWithTitle: _(@"Preferences...")
         action: @selector (runPreferencesPanel:)
         keyEquivalent: @""];
   [menu addItemWithTitle: _(@"Help...")
         action: @selector (orderFrontHelpPanel:)
         keyEquivalent: @"?"];
