I don't get it, how does it work?

You write the name of recipes in a list in the settings. To find out internal names of things, press F4 while in game and enable show-debug-info-in-tooltips. Now whenever you hover over a recipe or technology with the cursor, the tooltip will contain additional information, including the name.

Thanks! That's really cool

Thank you for the mod. It is a nice touch, to no longer have small wooden poles or stone smelters in the recipe list.

Hello, boss.
I've tried some combinations to hide the recipe, but it doesn't work. It always crash the game.
I tried to input the name, only the name, the name between ' " '. Nothing works.
Could you give an example, please?
Thanks.
