as in, show whichever version is referred to in a boost/embed/quote, but show the slider arrows and make it a "slider" so on touch interfaces it can be swiped left and right, like one of those stupid time scroller things that are popular for landing pages, and make one setting "show original or show newest" in the settings and respect that in the display when the original is referred to... so if someone wants to see the newest, it shows the newest, but when you swipe, it changes the tree underneath it as well
