This would be a fantastic feature and likely easy to implement. Once an ore node is discovered on a planet, its size could be displayed in the registry as "Gold deposit (Med) 100%," with "Med" indicating medium. Other size classifications could include "Sm," "Lg," or "XL." Currently, a lot of time is spent matching the registry with the map to determine if a node is worth placing an auto-miner on or even mining. Implementing this would completely eliminate that hassle.
