May I humbly suggest that this is rather tricky?
After clicking for a few minutes on the keys, I thought that the "customize you keys" feature wasnt already implemented.
What about some kind of warning that it needs to to be saved _prior_ to modifications?
Also, in this aspect of things, the cross to quit the game is rather small, i didnt see it the first time I played the game.
And what about refreshing the network list by default when you get there?
