I'm not thrilled about adding more config options. Would you mind providing some extra details regarding the motivation behind the PR?

I understand.

Firstly, it's a personal preference. I like having the possibility to customize things to my needs, but I do understand the maintenance burden of this.

In my case, I want to add the author and description for SEO purposes, but I don't want the author displayed at all, and I don't want the description displayed in the footer because it's in the placeholder of the textarea: https://notepadtab.com

Sorry @revolter, you will have to customize the footer include_file to suit your preferences.
