Suggestion: ability to hide mining/smelters by default

The production overview, especially with the bobs recipes, gets crowded with miners. Most people don't source raw ore for recipes but only plates.

Suggestion is to hide the rows w/ miners and maybe even smelters from the view by default.

Would be nice to have. A filter to hide or groups things together would be nice to have. I would prefer the default vie to show everything tho.
