Simple request, how about an "Autoloot" checkbox in the Interface Options menu? If enabled, automatically loots everything off a corpse. That way shift+right-clicking is not needed every time one loots.
Searched the forum, only found one thread discussing how to autoloot without pressing Shift; someone suggested an addon but it doesn't work. So it seems shift+right-clicking is the only method to achieve it right now. Would make questing and overall game play experience much smoother, in my opinion.
