   The Game Piece Palette is highly configurable, and can contain any combination of tabs, lists, and pull-down menus containing individual Game Pieces.
   For example, the window may contain a tabbed pane with two entries, called "Info" and "Armies", each of which contain a list of pieces.
  -Every component in the Toolbar should end with a Single Piece.
  +Every component in the Palette should end with a Single Piece.
   Since a typical game has many pieces that differ in only minor ways, you may find it convenient to clone Single Pieces.
   Also, the order of the pieces can be changed by dragging them within the configuration tree.
