Complex parts, especially visual parts, tend to have many features in their public interfaces, and consequently, their connection pop-up menus are very large. Because only a few features are used frequently, VA Smalltalk provides a way for you to show the most popular features on the pop-up menu, with an All Features choice which you can select to see the complete list if you need it. You specify the part's connection pop-up menu by providing a preferredConnectionFeatures class method that returns an array of the public interface names that you want on the pop-up menu.

Any public interface feature that you omit from this list (such as the ones you inherit) will appear under the All Features choice.
