1. Rejected because you cannot create objects in global scope which is the same as init (line 11 snowflake.js): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#only-use-init-for-initialization You can use dependency injection for Snowflake class to solve this issue. 2. Also rejected because snowflake.js and utils.js are not in js folder. So, importing with `Extension.imports.js.utils` will cause fatal error. You should import `Extension.imports.utils` and `Extension.imports.snowflake` instead. 3. log should only be available on debug mode: https://gjs.guide/extensions/review-guidelines/review-guidelines.html#no-excessive-logging 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
