Thanks for removing the Python scripts. Please fix these and your extension will be approved: 1. You cannot call that method in global scope which is the same as init (line 116 hct/viewing_conditions.js): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#only-use-init-for-initialization To fix that, you can make it as a function. 2. Remove stylesheet.css: https://gjs.guide/extensions/review-guidelines/review-guidelines.html#don-t-include-unnecessary-files
