1. You should also do this inside the callback function (line 57 extension.js): ```js this.addTimeout = 0; ``` 2. You forgot to remove the timeout in destroy: - line 91 lib/net.js - line 93 lib/mem.js https://gjs.guide/extensions/review-guidelines/review-guidelines.html#remove-main-loop-sources 3. Why the copyright year is 2020 in some files? I'm asking that because this is the first version of the extension. 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

Thanks so much for the prompt review! I've fixed the missing timeouts and set the source ID to 0 at the end of the callback in extension.js. The copyright is 2020 because that's when I started working on this extension and first shared it on GitHub (https://github.com/fflewddur/tophat/commits/master); let me know if that should be updated to 2022 since this would be the first public release.

No issue with the copyright year. You can update them if you want. Thanks!
