Can I control the display of cross hairs in a single view?

As a continuation of

How to display crosshairs in a single window. For example: the crosshair disappears when a single window is enlarged

Crosshair and slice intersections are two different things. Slice intersections will not appear if you only have one slice view in the view layout. If you enable crosshair display, it will be always visible in the slice and 3D views, regardless of what layout you use.

have you considered using the “Crosshair” functionality instead of the “Slice intersections” functionality?
