Not sure if this was mentioned, probably has been but..

How about a refresh button? Rather than having to exit the event page then entering it just to refresh it is kind of tedious. Adding a refresh button next to the close button would be very convenient. This would be extremely helpful during wars when you need to check the sent shield percentage, or the raid boss hp or to get rid of the boss defeated picture. A small addition can go a long way. And I'm pretty sure it's not that difficult to implement a simple refresh button. I could code that in my sleep xp
