• Use the addToTop variable to place the button where you want it. If set to true, the button will placed next to the forum/topic tools menu. If false, it will be added into each post next to the top and bottom links. See the screen shots above.
  

  var addToTop = false;

• If you decide to add the button to the top, use the compactTopText to customize the text or even add an image.
  

  var compactTopText = 'Compact';
  
  or
  
  var compactTopText = '<img src="URL TO YOUR IMAGE">';

• If you decide to add the button to the side, use the compactSideImg variable to point to your image URL. I decided to leave this as an image since that is a pretty small area and you wouldn't be able to add much text (if any) in that area.
