Hello Kalle,
Thanks for writing in! You can change the threshold to at least 1000 pixels. The problem is that you will have to manually edit the JS file and recompile it again so that it will work. All you changes will be overwritten when there is an X updates. Because what you are trying to accomplish requires a template customization, we would like to suggest that you use a child theme. This allows you to make code changes that won’t be overwritten when an X update is released. After your child theme is setup, please review how we recommend making template changes in Customization Best Practices.
Thank you for your understanding.
