Gwibber is a micro blogging client for the GNOME desktop for keeping tab on your Facebook and Twitter accounts within a single interface and getting on-screen bubble messages for account updates. It is the default micro blogging client for Ubuntu and is widely used by Linux users. One thing that Unity has brought other than frequent Launcher updates from multiple software are new Lens. There have been a number of separate third-party lens released for Unity such as Unity Place File Search. The Gwibber Unity Lens is another Unity Launcher lens which enables sorting messages, replies, posts, images, videos, links and private messages within Unity launcher.
