Game comments

[lightvector]

Add the ability to comment on games after they're played. The design of this should think carefully about how much it should share with with in-game chat. In fact, the in-game chat database and JSON API was designed to leave a bit of a foothold for this, although I don't know if that's ultimately the best way to go.

It would be cool to annotate games, not just comment on them. (Like PGN.) Sometimes a spectator will say "I didn't like move 43s because it's too slow," and it would be cool to be able to easily get to a gameboard with the played 43s. It would also be cool to step through the moves of a completed game and on each move see spectator comments that relate to that move.

The fun part is when a spectator suggests an alternate move. I want to be able to easily see the game board set up with the alternate move, not enter the move by hand into a planning window. Is there such a thing as PGN for Arimaa? That would be nice too.
