// First, line 121 not only sets the spacing between menu items, it is setting the size of the whole menu item

// The line that is provided in the file currently does the following:
// 1. Sets the width of the item to be the width of the text (this.item_txt.textWidth)
// 2. Adds spacing that is double the width of the font size chosen in the xml (XMLMenuItem.itemStyle.size * 2)
this.item_txt._width = this.item_txt.textWidth + (XMLMenuItem.itemStyle.size * 2);

// No spacing between menu items
this.item_txt._width = this.item_txt.textWidth;

// Keep current spacing, but add a little more (still based off of chosen font size in xml)
this.item_txt._width = this.item_txt.textWidth + (XMLMenuItem.itemStyle.size * 3);

// Choose a fixed width spacing of 10 pixels on each size of the menu item (20 pixels total)
this.item_txt._width = this.item_txt.textWidth + 20;
