title: Create drag-drop graphic when installing OS X application from dmg
body: <p>A lot of applications on the mac show a little graphic when the installer DMG is initially opened - the graphic basically allows you to drag and drop the app in that window without having to do it in finder (I'm not talking about package manager here).</p>
  
  <p>Any idea if there's a standard way to create that type of experience?</p>
