4. Go to "Misc"
5. Find "Home page tabs order" and at very begining add "dashboard" in demo it looks like
   1. Default after new install: dashboard,online_users,online_map
   2. All possible options : dashboard, online_users, pending_chats, online_map, active_chats, unread_chats, closed_chats, online_operators
