This seems really good!

"Reduces volume of sap extractors" is sorely needed. I don't understand why the trees scream in agony.

Have you tried to upstream any of these changes? Especially that volume adjustment seems like something that should just be fixed in the main mod.

Several of the changes implemented in py streamlined were folded into the regular py mods and are no longer included here, but I mostly just focus on this mod when making changes. Whenever anyone asks, I tell them they're welcome to copy whatever they like from here for that.

As for adding this to an in-progress game, the mod is designed with that in mind so no worries there. Any of the settings can be enabled/disabled whenever you like without issue.
