Wife's a healer, and always bugging me of what's the health of the boss at. I need to find anything that shows health of the target of my target, and also is moveable. Found one on here but couldn't get the frame to move which really sucked in things like wintergrasp and strand of the ancients since it covers up timers and data. Any suggestions?

Any of the unit frame addons will (should) give you ToT and be movable, take your pick.
