Two unrelated questions...

First, is there any way to have canvas lighting disabled by default? I, personally, don't like it and disable it manually with every new image...

Second, I'm having some weird pencil action. I love drawing with the pencil tool. My favorite of all. But whenever I draw sharp acute angles, I get these weird "pigtails" on the point.
In the attached image, the top angle is what I would expect when quickly drawing a point with the pencil. (I had to draw two separate lines to get the correct effect.) The image is zoomed in 200% to better show the problem.
