I'm tempted to make this a bug report, but for now I'll just point it out to you guys. Let me know what you think. OK, suppose I draw a wire from upper left, to lower right. Sometimes it forms an L, sometimes it makes a flipped L (a crude 7 shape). At first I thought this was random, I finally realized it's controlled by my facing. If I'm facing left, it does horizontal first (flipped L), if I face right, it does vertical first (upright L). Maybe this is an actual intended feature, but it seems very strange to me. It would be less confusing if it always did the same thing. You could still control it by simply drawing from the other end.
