All fields and tables that are set as "invisible" in the structure are hidden on user interfaces.

Interfaces include:
- Quick Report Editor
- Query Editor
- Formula Editor
- Label Editor
- Export window
- Import window

If a table is set as "invisible," the entire table is hidden from view so that users cannot see that the table exists, and thus cannot see its fields. If a field is set as "invisible" only that field is hidden from view.
