title: Cocoa Interface Builder's 'Attributes Inspector' like window
body: <p>I'm making a Cocoa application, and I would like a panel like the 'Attributes Inspector' in Interface Builder. So with big tabs on the top and collapsable/expandable groups. Does anyone know how I can do this?</p>
  
  <p>This is an image of the Attributes Inspector:</p>

  <p>So I actually want to make a window like the one shown in the image above.</p>
