Thank you for your enthusiastic feedback! I'm glad the add-on is meeting your needs.

I appreciate your suggestions. I understand how the current duplicate button icon can be counterintuitive.

Currently isn't possible to change the viewport size to avoid the toolbar from covering part of the page. However, I will investigate further to see if there's a possible solution.

If you have more suggestions or issues, feel free to visit my GitHub repository where you can open issues or pull requests. Although I haven't had much time in the last few months to work on the add-on, I'm willing to make updates when possible. Thank you for your support!
