I have an idea for something gO could do, but I'm not sure it'd be used at all (including by me) so I'll leave it alone for now.
Mostly just for the heck of it (but also in case anyone's curious, or might find it useful): My idea was that gO could represent a sort of "grasshop castle" with a single piece between the King and Rook (or whatever the two pieces are), with each of the two taking position on the other side of the intervening piece. (Of course the full notation would be isgO, but the g is the significant part).
It's probably too much trouble to actually code, especially since (as I already stated) I'm not sure that even I would actually use it; I just thought I'd share the idea.
