Does the line which divides the components in the blueprint editor have any significance?

[Killerbanaple]

While adding a component to one of my blueprints I noticed that there is this line that divides the top and bottom section of the component tab. I can’t drag stuff across it which makes me think putting things on top vs bottom may be important. Does this have any meaning?

I believe the line separates between components which have a scene component in them (like meshes) and actor comps that only have code (like char movement).
