Any chance of a refrigeration icon? This is my idea...
I modded a map with 64 resources on it. Several were bonus resources, and were food types (crab, citrus, apple, etc.). I figured that food could not be traded over long distances, until the advent of refrigeration. So I added this tech back into the game (it was there in Civ 2), making electricity its only pre-requisite. Then, I added more of the same food types, using the same icons, but changed the names slightly (crabs, fruits, apples, etc.) These new types I added near to where the old bonus resources had been, and set them to appear with refrigeration. The old types generated 0 trade, but the new types I set at +3 trade. So in gameplay, suddenly a civ has a source of food that they can export, if they discover this tech and find these resources within their borders.
When I looked at the tech tree, refrigeration had an electrical cord & plug, which belongs to the electricity tech. I need to change the civilopedia, and refrigeration having its own icon will do the trick!
