Automated lights is great (Vicio/Miner's Delight), but if anything it'd be nice to be able to disable it such as for when in areas you purposefully want to be dark (such as farming a spawner) for example.

Certain other perks may not be as immediately disruptive but giving the player a choice without repeatedly resetting or just foregoing the perk completely would be nice.

If the feature already exists, I haven't figured it out yet. The most streamlined suggestion imo would be to make clicking on the perks page toggle the perk.

hellfire has stated multiple times he will not be adding this feature.

Would be nice, but if you have to, have lights in the spawner. That way, when you go in, the mod says, oh, it's light. Better not place a light source there! and, it prevents mobs from spawning and killing you as well!

Also, I like the challenge of keeping it dark, but not putting lights there. So, nice, yes. Wanted by me, no.

(Also, I get if you didn't see it was suggested before. I made this suggestion After Searching multiple times for similar ones. I didn't see any, but apparently, it's been suggested before. So, don't be upset by it.)
