Other possibilities: Stuf, Chatter, AuraFrames? I use other addons but I doubt they have any control over the loot frame; OmniCC, Ovale, Autobar, etc.
Or do I need an independent addon that would allow me to move the loot frame? Any help is appreciated.
UPDATE: I found LootRollMover, but if anyone knows of anything else/better (or if any addons I listed actually control this thing) please let me know.
