This uses the Values plugin to keep the different panels below in sync from right to left. Any changes to the panel on the right are mirrored in the middle panel, whose changes are then mirrored in the left panel. Try changing various fields and pushing buttons to see the effects; then, be sure to examine the source to see how simple this is to use.
