  # As this script allows you to make a custom Menu I thought to make it easier
  # I would make it possible to add extra Menu Options from here
  
  # All you need to do is specify the Text to display, the icon and the command
  # The command must be in a STRING
  # Simply add to the array below :

  $game_ring_menu = [
  
   # Menu Option 0  eg. Item
   [Vocab::item, Cache::picture('menu01'), "$scene = Scene_Item.new"],
   
   # Menu Option 1  eg. Skill

   # Preferably Insert your custom Menu Options Here
   # Otherwise the existing Menu Options will return to wrong point on the Menu
