If you select an element in the GUI Tree, the element is highlighted on the canvas.

The Properties section allows you to make adjustments to the selected element.

The Description section allows you to add explanatory text or comments for every control or template that is used on the macro page.

Switch Back to Macro Page/Parent Template: This button in the header of the GUI Tree allows you to go back to the last macro page, template, etc. For example, after editing a template within a template, clicking Switch Back to Macro Page/Parent Template takes you back to the parent template.
