Lately, I got more Titanium and Saltpeter mines. When they are depleted, I have trouble to tell if those mines are Titanium or Saltpeter in order to send explorers to find the new ones. So, I would like either:
- Add more names to the exhausted mines; for example, "Exhausted Titanium Mine". We already have "Exhausted Granite Pit", "Exhausted Marble Quarry", and "Exhausted Quarry", so just like those.
- Or give each mine (and exhausted) an unique color. We can use the colors of their icons (Copper, Iron, Gold). However, both icons of Titanium and Saltpeter are silver, so one of the two mines may have a different color.
