[Suggestion] New Reply Warning on PM's

Hello,

I know this is already a feature when posting as if a users posts while you are creating your post you get a message that informed you that someone else has posted. I would like this also to be implemented into the messaging system. Such as when in a PM Conversation with more then just 2 users i think it would be a good idea to also show the message that there is a new reply to the PM before making your reply.

Thanks
