I frequently use the method of drawing partial circles where you specify two points on the circle and then "pull" out the third point to establish the arc. Almost always when I use this methodology the intention is that the first two points selected are the start and ending points of the arc. It would be very nice if this operation could be completed in three clicks, however after defining the third point you have to then choose which way the arc goes and the end point of the arc. I know this is a minor wish, but it is the simple things that make a smooth interface and help keep the brain clear.
