I found this mod after trying to find a chunk border/light level mod. Most do not work/are buggy, I was bummed when I realised that this mod has a working light level feature, but not chunk borders. I don't know a lot about programming but it would really make this mod whole if you could add this feature.

I don't know how people would feel about it but a cool feature I've never seen is a slime spawn overlay, similar to the light level overlay but it is green and shows where slimes can spawn. Would be very useful for building slime farms and mob proofing areas.

Wow, thanks for the speedy reply. I also noticed that this mod hasn't been updated to 1.16.3, I was wondering if you had an ETA?

Thank you for the workaround, I ended up having to use an alternative though because it hasn't been updated yet(?). I have to compliment that you seem like a very engaged dev and it's nice to see

Press F9 (the default) for chunk borders. It's actually a short cut to the built-in Minecraft chunk border fencing (F3+G). As for slime chunks I am not sure. Reason I am not sure is part of the game is searching for these slime chunks. I will have to think on that.

:) Actually I have been away a bit. Just getting back to updating my mods. I have not updated this mod past 1.12.2 due to time constraints.
