Add button to end attack without surrendering
Sometimes I just want to end an attack after I don't want to deploy any more troops so I don't have to watch it play out. This can save lots of time especially when all troops are deployed early and the extra 30 seconds after the update. I believe the outcome of the battle can be determined instantly so watching it play out is just for show. Instead of blocking more of the battle screen, change the current button to End Battle and the confirmation dialog gives Cancel/Surrender/Play Out choices.
