In the third function group of the Guideline module you can set the visibility, colour and position separately for each help element.
With these icons you can set the help elements visible or invisible separately for multiple columns, grid lines, guidelines, reference pin, printable area border, page borders, frame outlines and magnetic frame snap-range areas.
When any of these icons is selected with a left-click, the associated guide element becomes visible. A second click on the relevant icon deselects it and the guide element will no longer be visible.
