No way to retreive "non-active" displays

Robert Minsk <rmi...@...>

If I have a config with displays "a", "b", "c" and an active_display list of "a" there is no way to get to displays "b" and "c".  In fact reading in a config file and writing it back out will only write out display "a".  Should we add a methods to get the total number of displays not filtered by the active list and a method to retrieve the "non-active" displays?
