Hi Marc, I was able to get these sketch things tuned up for v3.

So for v3 once you have started a sketch brush stroke, if you right click during the stroke it will just be ignored instead of canceling the command like it does currently. If you right-click before you even start the brush stroke though it will cancel then.

Also in v3 when auto-repeat is turned on (when the little "Repeat" checkbox is checked) it should not matter how quickly you make brush strokes - currently if you do them too quickly it can exit auto repeat mode.
