Log Message:
-----------
REFACTOR: extracted logic to determine if the "current" frame is the largest within a set of frames, and added a method to enable toggling the display of 2 elements depending if the "current" frame is the largest. This new method would enable a smaller "disclaimer" to be used in all other frames besides the largest, as a hint to users that the other frames are still loaded from Wayback.
