// Need an easy way of getting and setting settings
// If a setting is not set, the default should probably be returned.
// That probably means that binds etc. should be per-key?
//
// We should probably store all settings in memory, and only load from storage on startup and when we set it
//
// Really, we'd like a way of just letting things use the variables
