I could use a bit of help on this. Unlike KNP, ANPs have subject which could be either pods or namespaces. I'm trying to find a good way to represent them

1. method one: we use icon and labels with a tooltip that explains each icon if you hover over it

2. Method two: we use text Judges? :)

@frozenprocess I personally think option 2 is better than 1. But is it possible to use icons before each subject selector for differentiation?

Yep, did some testing and it is possible to put an icon before each subject selector.

Admin network policy is going through some changes, and it will be renamed. However, this will not change our effort to have it ready for the Beta release in Headlamp.
