You now have a pretty good understanding of the Modifier tool and all that you can do with it. You had opportunities to work hands-on with the product, and see for yourself how it works. You made several changes to the windows themselves, even adding fields and pictures. You learned the secret of how to set the big line item boundary properly, add fields from the AutoLink table, and even learned how to properly line up the column labels. You made tons of changes to the window fields themselves, including changing the static text attached to checkboxes and adding tooltips.
Beyond windows, you learned how to make changes to global resources that affect the entire application. You can even add new pictures to the picture library!
In the next chapter, we are going to add the VBA component to the Modifier, and turn our changes into action-capable objects.
