Allow players to correct score estimation.
When opening a score estimation. Allow players to change the life/death status of groups by clicking on them. And also to change the status of a point between black/white/dame by clicking on it. Calculating the score by hand is slow, and having a score estimation done by computer is very convenient, especially for parts of the board that are very clear. But having to open an offline mode of the board and make changes to the board to make SE understand the state of groups is slow. Would be much each to follow the games, if you could just click on the given score estimation and adjust it directly instead.
This should be a requirement. KGS has this feature and works well. I have no doubt that kaya would forget such an essential feature.
