When you use a view wrapper part, VA Smalltalk only has to create the view wrapper initially and can create the window itself when it is needed. A view wrapper is an iconized representation of your secondary window, so you will also save space on the Composition Editor's free-form surface. All of the features of your window are available to you as features of the view wrapper, so the view wrapper can be used as if it were the actual window.

See Using view wrappers for details on using the view wrapper part.
