It might be nice if Extractors weren't the color of the vegetation, it can sometimes be quite difficult to find them, as they can tend to go invisible.
Blue or pink would be easy to see

Also, if on the radar extractor dots could be a different color to Mining Claims.
When you have 30 dots and 5 are extractors and 25 are mining claims it can get pretty messy tring to find things, particularly as the extractors are sometimes bugged and need to be 'retsarted' even though they had already been started.So sometimes you have to run around to extractors and check they are actually running.
Different color extractors, and different color dots.
Or, the ability to turn a Mining Find off from broadcasting on the radar.
