Chats come to life in Facebook

I reported that facebook has added a new feature in chat which shows where your friends are accessing facebook from. This time there is complete refresh of the chat interface with a light blue background. You can see the changes in the picture below.

Facebook is trying to unify the UI across Computer and Mobile devices. This change seems to be part of the transition. It look more like how chat looks in Mobile app.May be facebook is going to get small changes often.
