Actually, I didn't understand  why you grouped them with Difference
(even given your explanation of 'can produce completely different
colors'); I would have grouped them with Overlay, since they both
provide darkening ( on one side of 128) and lightening (on the other
side of 128),

In general I like these new groupings a lot, particularly the
positional correlation (add/sub, dodge/burn)
I'm a bit puzzled as to why Multiply is paired thusly with Screen --
Divide is closer to being the opposite of Multiply IMO (from a visual
inspection div(mul(x)) and mul(div(x)) are closer to the original x
than scr(mul(x)) or mul(scr(x)) )
