The user experience suffers when property names in the code do not align with the labels shown in the property editor. For example, the ArcItem object uses begin and end as property names, but the UI displays them as “Arc start” and “Arc end.” This mismatch can mislead users—especially those working solely within the property editor—into believing the actual property names are start and end. As a result, they may spend unnecessary time searching for nonexistent properties when trying to create bindings.
