The library window is a floating window.
In the Windows version this window can be docked.
When you open libraries, the
buttons with their titles are located in the upper part of the window. The library
shapes are in the lower part.
By dragging a library title bar with the mouse you can display this library in a separated window. When you click on a library's title bar, it becomes active and the library shapes that it contains are displayed.
Library shapes can be displayed as icons, text or as both icons and text.
You can specify this in the context menu of the library and library shapes, or in the View / Library Window menu.
For more information see Menus - Library Context Menu, and Menus - Library Item Context Menu.
For more information about working with libraries and library shapes see Shapes - Inserting a Shape from a Library, Libraries.
