I noticed with the new oxygen overlay that we're not getting as much information. Contaminated Oxygen was changed to Polluted Oxygen, but it has the same coloring on the oxygen overlay as regular oxygen. This makes it much more difficult to find areas where you might be producing pollution or where the polluted air might be leaking in from some outside source (like polluted water).
The overlay instead shows concentrations of gas, so if the polluted oxygen is in high concentration it looks the same as high concentration clean oxygen. Are there any further planned tweaks to the oxygen overlay that might help clear up the display.
