Blocking/Unblocking Contacts
Currently in Chatty there's no way to block a contact in the UI, either in a 1-on-1 chat or in a group chat situation. Simplest way to integrate this would be to provide options in existing context menus for blocking along with a view in preferences to manage/view your blocked context--here are the initial designs that elaborate on this.
