This option allows you to choose this style for the Summary window.
This WOW style Summary window has room for two quick bars to be docked inside the window.
Notice that with this style, the player health, power, and endurance status bars will shrink or expand from the middle as the levels change. In addition, the current value is shown above each bar.
Note: To move the window click and drag the button that appears when you hover over the area at the bottom of the left lions front feet.
