What do you need help with?

I noticed that cobble and dirt are used, but not netherack and I want to add that and cant remember if there was a command that does this in 1.16.5

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

There is a setting called acceptableThrowawayItems.
It defaults to dirt,cobblestone,netherrack,stone so unless you changed it it should already use netherrack.

how do I get baritone to also go though the portals, I have the setting on but its not going through them, like how does that work?

Baritone can't use portals to travel. The setting only means it walks into the portal rather than next to it when you run #goto portal (or #goto nether_portal in 1.16)
