Hello there! .o/
I have a little suggestion that might be hard to code or not but i believe its possible!
Split the enable option on electric furnace config like this:
Enable electric stone furnaces [ ]
Enable electric steel furnaces [ ]
OR
Add electric stone furnaces as a recipe ingredient on electric steel furnaces
So that way it won't clutter too much my inventory =P
Usually I don't feel like to use stone furnaces ... Sometimes its useful don't get me wrong but in near mid game i usually need a electric furnace and I usually opt to use steel versions instead ... if i used stone version it will clutter in my inventory for rare situations ...
Well... its just a suggestion anyway and thank you very much!!
