1. Please use a less generic for the default class you export in `prefs.js`. 2. Remove `stylesheet.css` since you are not using it: https://gjs.guide/extensions/review-guidelines/review-guidelines.html#don-t-include-unnecessary-files 3. Don't use `this.` since that won't allow the garbage collector do its job after window close (line 9 prefs.js). You can attach that to prefs window though: ```js window._settings = this.getSettings(); ``` 4. No need to use argument for `this.getSettings()` since you have specified that in extension.js.

If you need any help with your extension you can ask us on: - [GNOME Matrix Channel](https://matrix.to/#/#extensions:gnome.org) - IRC Bridge: irc://irc.gimpnet.org/shell-extensions
