The settings bedrock of the Realistic Farming mod ecosystem. SettingsHub is mod 4 in the load order. Companion mods hand it their settings and one callback; SettingsHub owns a throttled async queue so heavy setting changes (rebuilding a large array on a slider tick) apply smoothly in the background instead of freezing the Lua thread, and it routes admin-only changes through the server so multiplayer stays consistent.
There are no settings of its own to configure. Install it, keep it loaded, and let the companion mods use it.
