But you don't want to set the next branch to default, right?

Recommendation: You can add PR templates to your repo, allowing you to predefine the text people see, including checkboxes like:

• [ ] I've made sure code is properly indented / formatted
• [ ] If this is anything but a bugfix that specifically targets a released version, I'm doing a PR against next, not any other branch.
• [ ] My hovercraft is full of eels

Thanks for the hint! Now it is just a matter of doing.

But you don't want to set the next branch to default, right?

Yes, because the next branch is the development branch and sometimes the code is broken.
