Hi Marky,

re:
> Is there a way to make an Arrow to be screen aligned too?

There is a setting for it which isn't exposed in the UI but can be set through a script.

If you put in this for the command part of a shortcut key it should switch the property for making the arrowhead plane rotate to face the viewer on selected dims:

script:
var objs = moi.geometryDatabase.getSelectedObjects().getAnnotations();
if ( objs.length > 0 )
{
objs.setProperty( 'rotateArrowheadPlaneTowardsViewer', !objs.item(0).rotateArrowheadPlaneTowardsViewer );
}
