Config file or options panel to select wanted sub-features

Would be great to add a feature at a later date that allows users to enable or disable sub-features (like disable the thruster limitations) via an in-game menu, commands, or a config file.

However, complications arise for multiplayer vs. singleplayer, as multi will need a way to sync the servers config to the players reliably and securely 🤔
