I'm using xcode Version 4.2 (Build 4C199) with iOS 5.0.
I'm following the Apple's documentation at: http://developer.apple.com/library/ios/#documentation/cocoa/Conceptual/UserDefaults/Preferences/Preferences.html
When I tried to add Settings.bundle, described under "Adding the Settings Bundle" section, I'm not getting all files under this bundle; Like after adding this bundle, I had only Settings.bundle at root of my project and there isn't any Root.plist and en.lproj etc;
Screenshot of my project:

So after reading some other questions here, I found that I have to right click on settings bundle icon -> show in finder -> right click on finder item -> show package content; Now I can view Root.plist and other items; But my question is is there a way to view the hierarchy of Settings.bundle inside xcode project navigator?
The next query is how can I add Child plists under Settings.bundle? As right now I'm unable to expand Settings.bundle in my project navigator;
Open the package in Finder. Drag the files into the project file list (but make sure that you remove them from all build phases)
