    Demo Element Justification In A Window Using A Text Element That Expands

    How to Justify elements on 1 row to be left, right or left, middle, right

    Additionally, locate these buttons at the bottom of the screen

    The key concepts to use are the newly added expand_x and expand_y

    To get 2 buttons to be all the way to the left and to the far right, then
        you want to place a text element between them that expands
    If you want a third button that is centered, then add TWO Text elements, one
        on each side of the middle one
