Did you ever got messages on Windows Live Messenger when you are busy and do not want to chat? Then you would definitely have to open up the chat window and read the sender’s message, in fact, wasting a lot of time. Right?
But don’t worry, I have found a very neat plugin by which you can easily see all your incoming chat messages on you desktop without the need of opening each window to read. Of course you can reply to the important messages instantly or reply to them later. :)
