CustomBar is a bar that is always visible, much like the taskbar. Unlike the taskbar, you can put pretty anything you want on it. This is accomplished through a scripting/plugin/skinning system that is powerful enough to create some basic apps in. C++ plugins can be used to further extend functionality. This allows users to create or download additional components for their bar. An editor is provided for easily creating bars.

CustomBar comes with many standard "prefabs", including Winamp controls, web search, volume controls, shortcuts, a mini notepad, system stats, template copier, recycle bin quick-empty, clock, shortcuts to special windows dialogs and much more. Additional prefabs can be downloaded online.

Full skin support allows CustomBar to be adjusted to fit any Windows theme. The small height of the bar makes it possible to use it without losing large amounts of precious screen space.
