Using Libraries via the Control Panel

Libraries can be easily marked for use in the Control Panel by clicking on their activation icon (which changes its color to indicate that this library is being used), or by selecting "Use" from the library's context menu. Through the context menu of the "Libraries" entry in the Control Panel it is also possible to use all of the libraries or none of them.
