Now, black ko and white ko use the same sign sequence, such as black triangle, white square,etc.what i want is black ko and white ko can use the sign sequence separately, such as black triangle, black square and white triangle white square. I think that might be clearer in diagram.
it would be better that the user can define and configure his own sign sequence .(这句我自己加的,自己定义符号和顺序)
