title: Unity3D: Make UI stay top-most
body: <p>I have a game object with a UI <code>Canvas</code> in it and several child UI objects inside that and want to make this game object/canvas to stay top-most above all other possible UI layers.</p>
  
  <p>The purpose for this is a FPS/Counter/Stats UI that can be dropped into any game and therefore this UI should stay top-most. However when testing with some Unity3D projects (UFPS for instance) I noticed that it's own UI puts itself in front of the UI of my FPS counter.</p>
  
  <p>Can somebody give me a hint how I can achieve my FPS Counter to stay topmost?</p>
