After so many updates I'm still so confused as to why there is not a better system for selling unused parts for coins. I hope to soon see a system where you can click and drag or have a check box to select multiple parts to sell. I also think it would be nice to have an option to change how the parts are sorted like by overall rating across all parts, by total power, health, or damage. It would be nice to see parts introduced to counter the darts.
