I like that idea for the %. It's actually quite intuitive for the symbol's conventional meaning. The only question is, what effect would that have on a Rook on a rectangular board? If the board is 12x16, would the half-Rook move six spaces sideways and eight spaces vertically? (That actually would make the most sense to me.)
As for using ' and " to "retire" d, I think the letter would have to be retained for backward compatibility. Otherwise, I think we'd have freed the L and J atoms by now. (I personally would welcome seeing all three characters freed up for potential new uses -- like, an atom for Bison (CZ), mainly for use with Cheetahs, Sabertooths, and related pieces, which I wouldn't try to do with the smaller number of free atoms we have right now.)
On a (mostly) unrelated note, I'm finding trouble when I try to put more than one pair of parentheses into a move, whether nested or sequential. For an example of the latter, I've tried expanding the Springer's pya(b)K move so that it can bounce off more than one target, but pya(b)(pa)K (or even pya(b)(pa)2K) doesn't yield anything but an error message ("No atom at end").
PS: With some experimentation, I've found that shQ and shK yield "all directions except forward and backward," while vhQ and vhK yield "all directions except left and right." I just thought I'd point that out; I think it'd be worth documenting. :)
