How can entire panel groups be reordered in a design application?

Reordering entire panel groups in a design application is often accomplished by manipulating the interface directly, which typically involves visual gestures. Dragging the double gray line at the top of a panel group allows users to reposition the entire group within the workspace or user interface. This method provides a quick and intuitive way to organize the workspace tailored to individual workflow preferences.

The other methods listed, while potentially applicable for other functions, do not specifically pertain to the direct action of reordering panel groups. For instance, right-clicking may bring up a context menu with options, but it does not provide direct manipulation for rearranging panels. Similarly, using keyboard shortcuts or drop-down menus would be more limited in functionality for this specific task of reordering groups, emphasizing the practicality and efficiency of the drag-and-drop method using the gray line.
