P: Ability to snap to Pixel for shape/layer creation and transform

Precisely. I think the default should be for everything to snap to pixels. It gets tedious having to make so many 3200% adjustments just because a path is off the pixel by a tiny bit.

I assume you're talking about vector path/shape pixel snapping, as the bitmap tools mostly snap to pixel anyway? If so, then I'm all for it. Most of the time I want everything to snap to pixels.
