Open All Bags was missing from the Game Options window for about 6 months after release. Then it was secretly added without fan fare and remained a hiden feature for another 6 months or so until they changed the default key maps. It was a frequent feature request on these boards long after it was available in game.
Previous target had a similar history. Most ppl STILL don't know its there and its HUGELY useful for raid healers/buffers that need to quickly swap from MT to someone else and back. Particularly if neither is in group
