vanep - The two-legged button part works great, but a few cosmetic issues:
1) The preview image in the parts bucket still has the four legs
2) The legs are actually kind of hard to see on the board. This was also true of the other button, too, but only having one makes it more difficult to see. I'm not quite sure what to do about this, unless you offset the legs a little so there is more of them to see.
3) Having rubber-band legs would also be helpful.
