No, I do not plan to integrate with gnugo (but maybe some parts of the code could be reused for that…)

The game will only load a sgf library and allow to play inside the differents game recorded. Explanations for bad/good move are supposed to be in the library, not in the game itself. For now I'll reuse the datas from uligo, but you can get other problems in sgf format on the net (goproblems allow you to sell their library, but I didn't tried them).

Take a look to uligo to see what I want to get for my game.
