First is easy, please fix the english locale of the enable coal recipe option for settings. "on recipe cool" just doesn't help people understand wtf it does.

Second, can you please add a startup setting option for how many coal to make per wood? 150 per wood is too much, even for me. I'd default it to 8 myself.

will work on that lately, thanks for pointing it out for me. This is a adapted mod from 1.1 version, so I am not the person that write all the code and locale. so there will be unreasonable code / functions that I haven't see and changed.
