This is similar to this completed suggestion: Avoiding Repeat Opponents with Find Battle and being able to cancel it However I think that having the opportunity to cancel a challenge on the challenge window will be nice as well. So far the only ways, at least from what I can tell, to cancel a challenge is to log off or change your team. That's kind of a nuisance. Maybe it will be possible for the challenge window to stay open until the opponent rejects or accepts your challenge. Obviously, this isn't a real pressing issue, but it will make it more user-friendly.
