Give option to clean up battle logs
It isn't that necessary, but I personally would like it very much if you had the option to wipe clean the logs when you decide to. The logs would appear as if you've never had an attack before.
Reason is: With that you could easily test out new bases on how they work. After you chanced your base you could just wipe it clean and only see attacks that were done while you already had your new base.
Might be unnecessary to most players, but I just wanted to share the idea because I'd really like that feature.
