Outbar.NET

Outbar.NET is a component pack allowing you to incorporate a side bar control into any of your .NET applications. Outbar.NET is designed to bring to your application the "look and feel" of the Microsoft Outlook. The side bar (now commonly known by various names akin to Outbar) is one of the brightest parts of Outlook's interface. It is elegant, convenient, and intuitive: often unnoticeable yet taking the major role in the interface navigation.
