Notification on main screen that someone is being attacked in war

I think a good feature on the main base screen would be to have a small status window or text that displays an attack indicator or a message that says something like "PlayerXX under attack". This way players don't need to sit on the war map waiting for an attack to start to watch the live replay. They can see the indicator and quickly get onto the war map and watch the live replay. Maybe they can have a setting for each user to toggle this feature if it gets annoying for them or if they don't care to watch live replays.
