Improve the visual connection of Parent and Child nodes - like the Logseq Bullet Threading plugin

Explain the problem as you see it

In both light, but especially dark modes, I am struggling to see the visual connection between nodes, especially in a long list of child nodes.

Why is this a problem for you?

It is easy to lose ones place in the hierarchy of nodes, and the context of any one node. This makes navigation and understanding the connection of things difficult - it adds friction to my understanding of information.

Suggest a solution

I would love to see a simple improvement to the colour of lines connecting nodes, like I have seen implemented in the Bullet Threading plugin in Logseq (see image)
