Xcode's Interface Builder UI Problem

I've only started developing using Xcode with Interface Builder and finding it difficult. Apple should use one-window for Interface Builder so when switching between Xcode and Interface Builder would be easier, not utility windows scattered around, and have to click on to different windows just to put in front, and you can see the guts of Xcode at the background. Thanks to a free app called Backdrop, it makes it more organized although you have to click to it's icon to able to use it. It is available at the Mac App Store for Snow Leopard.
