Preferences toolbar without BWToolkit

Since Xcode 4, using BWToolkit isn't really easy. In fact, it's not even possible in IB.

Is there some sample code out there how to create a "preferences-type tool开发者_开发问答bar" without BWToolkit?

Yes, MVPreferencesController as used by Camino. See here for Doxygen documentation. It displays NSPreferencePanes registered using a plist. It's pretty easy to work with and customize for your purposes. You can also use the Camino project as a source of sample prefpanes.
