Management of Friend Requests

Its about more detailed management of friend requests. In pending (of friends list) there shud also be the requests sent by user to others (not only recieved requests) So we can cancel the requests. And also if a friend request sent more than once it shud give a prompt "A request has already been sent" instead of same prompt "You have sent a friend request " for more than once. It happens if u forget u ever sent them request.
