Agree with your suggestions, though I do target the mineral bits with the contact list when they are in a perfect line, and that works out pretty well. Utilizing the headlook to activate the UI while still seeing the cargo scoop HUD.
I like that the mining requires effort. Seems like without the high end metals, that it isn't worth the effort though, sometimes even compared to the most common contracts to ferry goods back and forth.
Early on, I was hoping they were going to make a method of mining that used drones (since I feel that is actually the most practical way I could see it developing as an industry.). They could even make the auto-drone method a reasonable percentage less efficient than picking up the goods manually.
Ultimately though, mining gave me a better understanding and skill with piloting the ships that I used for it. I like it as a pilot skill honing mechanic as well.
