undo feature

It would be nice to be able to undo the last move. Even better would be if you could rewind to any part of a game and try a variation.

Thanks for the suggestion. Trying variations makes sense for play against GNU Go but not so much for playing against other players. However I do hope to have a variation editor so one can try out other paths and add comments.

As for the Undo feature, I would like this too to avoid miss-clicks. This is especially a problem with mobile devices. I am thinking a "confirm" move button would make sense in that situation, but for fast play on the desktop I think a confirm button would get annoying. I'll need to experiment with a few ideas to figure out the best user experience.

you could maybe use an undo link/button, with a grace period, like for gmail email sending: you get a certain amount of time to undo a move.

@elisehuard, thanks for the suggestion. The only problem with this is that the move cannot take place until the undo grace period has ended. When a game is played live or against GNU Go the wait will be really noticeable. It is definitely something I want to improve though.
