1. `Tweener` is a deprecated module. Please remove it for the next version. You can use `ease()` instead (supported on 3.36 and higher). For example: ```js widget.ease({ x: newX, y: 10, opacity: 100, duration: 2000, mode: Clutter.AnimationMode.EASE_OUT_BOUNCE, onComplete: () => { log('Animation is finished'); } }); ``` More about animation mode: https://gjs-docs.gnome.org/clutter10~10_api/clutter.animationmode 2. Don't create objects in global scope (line 130 prefs.js). Create gsettings object inside `PrefsWidget`. 3. What's the reason for disabling extension in init? (line 113 extension.js). You shouldn't need that. 4. enable and disable function shouldn't throw like that. Please remove those try catch block. 5. Where do you remove those timeouts you are adding in enable? https://gjs.guide/extensions/review-guidelines/review-guidelines.html#remove-main-loop-sources 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
