I remember that in the past Messenger Plus version, like 3.X, there was a pretty cool function that enables you to know who have opened a message box with you.
For example, when a person open a message box with you, there will be a small notifier at the bottom right corner to let you know. I have just installed Messenger Plus! Live but unfortunately I couldn't find this function.
My question is where can I find this function or has it been released yet? Thanks in advance.
