Global is the same as init. Create `SETTINGS` inside `buildPrefsWidget()` as local and pass it to the `EmojiSelectorSettingsWidget`: ```js function buildPrefsWidget() { let widget = new EmojiSelectorSettingsWidget(ExtensionUtils.getSettings()); ```

Perfect, thank you for your support! Just a few questions, just to avoid making you review indefinitely, when passing settings to the `EmojiSelectorSettingsWidget` like you showed, how can EmojiSelectorSettingsWidget get this variable like in a Constructor? Maybe something like this? ```js const EmojiSelectorSettingsWidget = new GObject.Class({ Name: 'EmojiSelector.Prefs.Widget', GTypeName: 'EmojiSelectorPrefsWidget', _init (params) { this.settings = params.settings; let builder = new Gtk.Builder(); builder.add_from_file(Me.path+'/prefs.ui'); this.prefs_stack = builder.get_object('prefs_stack'); this._loadPrefsPage(builder); this._loadAboutPage(builder); }, ... ```

like this: ```js _init (settings) { this.settings = settings; ```
