In the panel, next to the number of joints, display the name of the current bone while sketching joints. Displays "Bone offset" when the next bone is not connected. Displays "Done" when all joints have been draw (note: you can draw more joints then needed, the retargetting algo will use the most useful ones).

Convert gesture is back. This time, it's a 3 straight line that cross itself once gesture (like drawing a triangle and recrossing the first line).
