Add a line from mining tower to active mining area, only visible when clicking tower.
First this is a wonderful game and I think it has provided me tons of entertainment for the money. Thank you. I have a request to add to the game. It would be helpful if when I click the mining tower if not only did that towers work area turn yellow but if a line went from the tower to the area covered. Later in the game and especially on larger maps the working location may easily be nowhere near the towers location. This visual cue would only be needed when the tower is clicked.
