Which mod to easily increase enemy spawns ?

Hey guys, I'm looking for a SIMPLE mod to encounter more enemies. I have checked brutal company, lethalquantities, lethalvariables but they are all overly complicated with too many useless features and the need to configure everything line by line with unknown number references. It's a pain.

I just want a mod that allows in a few lines to increase the monster caps and/or make them spawn sooner or faster. That's it. No need to configure entity by entity or moon by moon with surprise mod breaks.

Also, I don't understand how the game spawns work. I can't grasp what the differences between monster weight and rarity and spawn chance are. The modders seem to never agree on the meaning of these terms so I don't know what to increase or decrease to encounter more monsters. Could you please explain it to me like I'm a golden retriever ?
