I have suggestion. Develop a Clan War chat app. Where all the chat related things can be done. Like whatsapp. Right now what happens is that when I am outside the app I cant see the clan chat and also cant make strategies as decided. Through the app we would be able to contact Clan members at will without opening the whole game. Also many features can be added like donating troops from that app and also clash of clan smileys and real tile notifications. Private chat to members.
This can be really helpful
