The only way to know if there is someone attacking or getting attacked in a clan war is to go into the clan war screen. It would be nice if there were some sort of indicator in the main game screen that let you know a battle was raging. For instance, the war icon could flash, or there could be a small flashing indicator that came up when a battle starts.
Would also be cool if there were a way to show the score on the icon but there may not be room for that.
