yafsR should be no problem (yafscabyaifzR). y(a)5K is not valid XBetza (as it includes yK), but I suppose you mean some kind of area move. If there is more than a left-right choice it is indeed not possible to retrace the path using q and z. This could also be solved by a new directional modifier that would do what i does for the range of a continuation leg: mimic a previous deflection.
It doesn't seem obvious to me, but that's probably just me.
Well, you unload something that disappeared elsewhere. And if p' means friendly hopping, it seems natural to make u' mean friendly unload, i.e. that you don't unload the captured piece, but the moving one.
(the "load" spot won't always be the end)
I don't get that. A moving piece would always have to follow the entire trajectory; that is the basis of XBetza notation. So how could it end up anywhere else than at the end?
