Little Feature that i think SuperCell should add in!!!!

Just a small idea i have or heard somwhere:
+Increase the amount of space u have in the letter box or the clan description!
+Now you will be able to write and then send an invitation to the player you want to invite.
+You will now be able to send a letter to other player beside ur clan ( Can only be sent one time in 24 hour)
+Private box chat(next to global and clan box) where only co and leader have the ability to chat
+Be able to save replay directly into your devices
+Send back a message if they accept your in invitation or not!


Thankyou for reading! Leave suggestion tell me what you think, what should i add to this to made it perfect?
