Actually, I think moving the focus frame would be very helpful as well. There are a few boss encounters, Ony being one of them, where as people usually call out directions n,s,e,w, etc. during breaths. Being able to view the map in these instances is very helpful to me. I usually use my focus frame for my tank for heals on my priest or for passing them threat via macro without having to change targets on my rogue. I'll try the /nui minimap option you suggested. But the possibility of a movable focus frame does sound very nice.
