Looks good. just a small suggestion—could we add some info for fix.optimize-sponges? Maybe something like:

fix.optimize-sponges.enabled: true
fix.optimize-sponges.info: Optimizes sponges by doing ABC

I have been trying to do that for any new settings added to Poseidon so at least the config has some documentation.

fix.optimize-sponges -> fix.optimize-sponges.enabled

fix.optimize-sponges -> fix.optimize-sponges.enabled

Look, the code works so I'm leaving it as is. If the muffin man wants it to be a certain way, he can merge it and change it himself. The code is offered as is.

Coming up on a week now @RhysB. I added the info thing to the config.
But if the .enabled thing is really that important to you, you're gonna have to add it yourself. I have way better things to do. I'm sure you do too, which is why it only takes one click for you to merge this. I don't mean to be an ass, but if you want the config changed, you're gonna have to do it yourself once this is merged. I have my own server to run, and I was doing this as a favor to code because I thought I would be able to merge it myself, which I can't, so now I've just wasted my time basically. If code submitted this himself, I would've just merged it as is instantly because there's a grand total of like 4 people that use this thing and something tells me none of them will care about the config.
