This is more of an opinion but I feel like this criticism may help.

Caves are way too crowded sometimes: its hard to see ores, I cant walk 5 blocks without bumping into something, and vines are constantly slowing me. Maybe tone down on the amount of stairs,slabs,vines, and etc.

Adding on to this, it would be nice to get a config option for disabling certain parts of generation, such as speleothems or roots

This get cranked up to ten if you use "YUNG's better caves" with your mod. Certain tight space areas get impossible to move in.

I just put a comment at curseforge about this. I also am not seeing mobs spawning due to the clutter. Not enough are blocks to allow mobs to spawn.
