Clan war: attack in progress notification over war button

During a clan war its fun to see when other clan member attacks and defense live! but I have to sit and wait in the clan war view without anything to do.
I know there are replays, but live is so much better because you don't know the outcome. And we all know how popular twitch is.

It would be nice to have a notification over the clan war button, so that I know something is going on there.

I like this idea though it may be slightly uncomfortable for people that dont want all the spectators. Notifications will definitely increase the amount of people watching a raid. I do like the idea though. Another thing I would add is that they allow us to start watching live at any point of the raid, not just the beginning part.
