When watching someone's drawing bring drawn, in the bottom of the drawing area (above the letters) there are two icons.
I know the one on the right, which looks like two arrows around each other, shuffles the letters around.
What does the one on the left do? It looks like a curved arrow pointing to the right, but I've not been able to notice any function. I thought it might be to redraw the opponent's drawing, or to skip to the final result, but it never seems to do anything when I press it, either while the drawing is in progress or when it's finished.
