Application scope is a foundational concept in ServiceNow application development. ServiceNow documentation describes application scoping as a protection mechanism that identifies and restricts access to an application's files and data. In practice, scope defines an isolation boundary around an application's artifacts, such as tables, scripts, UI components, and other resources. This boundary helps prevent unintended interference between applications and reduces the risk of naming collisions or cross-application impacts. The scope model also works together with Application Access settings, which allow administrators to specify what parts of an application are accessible to other applications. By default, scoped applications are designed to keep resources private unless explicitly shared through access settings or cross-scope privileges. Because of this, the primary purpose of scope is not backups or UI design control, and it is explicitly not meant to enable unrestricted updates across applications. Instead, scope exists to define and enforce boundaries so that an application's resources remain isolated and protected unless intentionally exposed.

/concept/c_FormDesign.html
The Form Designer is a graphical interface for creating and customizing forms. The following statements are true for the Form Designer:
* To add a field to the form layout, drag the field from the Fields tab to the desired destination on the form. This will add the field to the form view without changing the table definition.
* To create a new field on a form's table, drag the appropriate data type from the Field Types tab to the form and then configure the new field. This will create a new column on the table and add the field to the form view.
* To remove a field from the form layout, hover over the field to enable the Action buttons, and select the Delete (X) button. This will remove the field from the form view but not from the table definition.
The following statement is false for the Form Designer:
* To add a section to the form layout, drag it from the Field Types tab to the desired destination on the form. This is incorrect because sections are not available in the Field Types tab. To add a section, click the Add Section button on the toolbar or right-click on the form and select Add Section.
