Either a Encyclopedia page or hovering over a material/ingredient icon to show what it could be used for would be great! Trying to check all my artisian buildings to see what ingredients are used for what is really grinding.
There's something that might be what you are looking for in the recipe panel already - by changing the mode from "product" to "ingredient" and searching for a resource, you can see all the palces where it can be used (you can also select "show all" to see even the locked recipes).
Let me know if this is what you meant. Or, if you already knew about this, if there is anything we could do to this panel to make it more usable for this purpose.
