Which tool allows you to modify and configure the display of the Studio 5000 Logix Designer application?

The Workstation Options Dialog Box is the tool that allows users to modify and configure various display settings within the Studio 5000 Logix Designer application. This dialog provides comprehensive control over settings such as graphical user interface preferences, zoom levels, and display options for various panels and windows within the software. By manipulating these settings, users can tailor their working environment for increased efficiency and comfort, adapting the software's interface to better suit their specific needs and preferences.

The other tools mentioned serve different functions. The Path Toolbar is primarily used for navigation within projects rather than for configuring display settings. The Online Bar provides functionalities related to monitoring and controlling online processes but does not allow for display configuration. The Project Settings Menu focuses on project-specific configurations rather than broader display preferences, making it less relevant for modifying the general appearance of the interface. Thus, the Workstation Options Dialog Box is clearly the best option for this purpose.
