What do these settings do? I'm not seeing any effects, when I tinker with them. Thank you.

It's somewhat of an advanced setting but basically it's used to style the nodes/links in specific nodes or categories. I'd need a link to see what's going on as to why the settings may not be working though(from the screenshot you have).
