New Facebook Feature Chat Sidebar for Smaller Screens On Desktops

After we saw YouTube's Multi-Angle View Feature, we now have Facebook rolling out their new feature. Unlike YouTube, this is a small sidebar feature. 

With this feature when the user re-sizes or crops their browser with facebook on, a chat sidebar appears from the right. When you click on the chat photo the regular chat box opens and you hover over a photo the sidebar expands to the regular chat sidebar.

As this is a new feature, it has certain limitations. The chat sidebar only appears to a certain level of width of the browser and when cropped further it disappears, and becomes normal when the width is further increased.
