1. Rejected because you are creating objects in global scope which is the same as init ("const settings = getSettings();"): https://wiki.gnome.org/Projects/GnomeShell/Extensions/Review#Only_use_.60init.28.29.60_for_initialization Please remove that. You can use dependency injection that comes from enable() or buildPrefsWidget(). In that case, you only create settings object once. 2. Please remove `src/utils/getSettings.js`. You can use this instead: const ExtensionUtils = imports.misc.extensionUtils; and add this to metadata.json: "settings-schema": "org.gnome.shell.extensions.dockershortcut", in enable() or buildPrefsWidget(): let settings = ExtensionUtils.getSettings();
