Remarks

The Enhanced Input User Settings class is a place where you can put all of your Input Related settings that you want your user to be able to change. Things like their key mappings, aim sensitivity, accessibility settings, etc. This also provides a Registration point for Input Mappings Contexts (IMC) from possibly unloaded plugins (i.e. Game Feature Plugins). You can register your IMC from a Game Feature Action plugin here, and then have access to all the key mappings available. This is very useful for building settings screens because you can now access all the mappings in your game, even if the entire plugin isn't loaded yet.

The user settings are stored on each UEnhancedPlayerInput object, so each instance of the settings can represent a single User or Local Player.

To customize this for your game, you can create a subclass of it and change the "UserSettingsClass" in the Enhanced Input Project Settings.
