[Edit] While at it, I also expanded the capabilities of the Move-Definition Aid to understand leaps to the 4th ring. (As I already did yesterday in the Checkmating Applets.) Originally the 4th ring was only there for seeing when you had defined a rider, or for cutting the range of a slider. Perhaps I should increase the size of the panel, so that you could also see or enter 5th-ring moves.
Given my love of Fifth-ring pieces, I'd consider this a boon. ;)
