You now have the ability to anchor Items to the center of the frame. AnchorCenterX: 0 will anchor a item directly to the vertical center of the frame. AnchorCenterY: 0 to the horizontal center of the frame. Negative numbers go left/up from the center, positive numbers right/down.

More work to come to deal with connected items such as rectangles made up on connected dots.
