Replay viewer with movements
So like when you see a replay that you made and it looks really cool but you don't know how you did it, why not have a button you can press that shows the movements of the limbs moving up or down as precisely at the moment of it being done as it you were going through a match again to see exactly how you did it to improve and replicate your replay exactly. The button can be the = or something that is not in use.
