1. Not needed to use line 119 `extension.js`. for example, this is how you can get GNOME settings with no issues: ```js new Gio.Settings({schema_id: 'org.gnome.desktop.background'}); ``` 2. Please use `connectObject()` and `disconnectObject()` so it is easier to track for cleanup (`extension.js` process only). 3. better to use `destroy` function directly: [Extension Best Practices Guidelines: Widget Destruction vs. Signal Connections](https://gjs.guide/extensions/review-guidelines/best-practices.html#widget-destruction-vs-signal-connections) 4.
