Which tool is used to drag an icon to observe design changes?

The manipulator tool is designed to provide users with the capability to interactively adjust and reposition objects or icons within a design interface. By dragging an icon with this tool, users can observe real-time design changes as they move the object. This functionality allows for intuitive modifications, enabling designers to see the effects of their adjustments immediately, which is crucial for creating precise designs.

The manipulator is integral in various design software because it effectively combines the ability to select, move, and edit objects seamlessly. The immediate feedback received while dragging the icon illustrates how modifications impact the overall design, making it easier to achieve desired outcomes.

In contrast, the other options do not specifically serve the purpose of dragging icons to observe design changes. The slider is typically used for adjusting values within a defined range rather than directly manipulating design elements. The adjustable tool generally refers to tools that allow for fine-tuning adjustments but may not specifically focus on dragging icons. The change inspector usually serves to track and analyze modifications made rather than facilitating the interactive dragging process.
