Improve the Displaying differences, on the Viewport, between Assigned Hooks (as Object Modifiers) and Parenting Relations

The dashed lines from both kind of Relations (Hooks and Parenting in my example) have mostly identical design Displaying… besides the fact they have the same default Color (Black); sometimes you can see the dashed line but you cannot see its ending (which in the case of a Hook would be a Black, small filled square).

It would be relevant if the whole design of the dashed line was made different alreadty (other softwares do that); but here some generic examples:

The Color could also be different by default from the base Parenting Relation, so that it would help in presenting Hooks as a more special Relation, giving it a better identity in Blender; because they are a special feature.
