Can I work with you on improving this?

It doesn’t make sense to display “next/previous” arrows on pages that visit them in chronological order. I’ve created a customized version of this plugin that visits posts in the same order as now, but pages in menu order. I also added an option to activate a “hierarchical option” to only display navigation on pages when the target is a child page — because generally there are pages you don’t want people to access in this way.

Are you open to incorporating these changes into your plugin?
