I just read @jorgev’s comment here and I realized that most addon devs don’t understand the review process and why it takes long. I did not know that injecting a script will bring a slower review process than using the API.
Is there somewhere a list of best practices for having a fast review process? There are a lot of people complaining that their addons took a lot to review. I have 5 small addons and they all took under 24h to review. Maybe if you promote in the Addons blog a list of best practices people will follow them and there will be a reduced level of effort on reviewers and devs will see their addons published faster.
