This one is basic and should exist in the mod as the config text might be confusing for people.
I would imagine that a preview would be shown of how it would look like and how it would look. Something to attach a link in a separate box next to your text on that part of the screen would also be welcome.

These are just my ideas and you don't have to add them.

This mod isn't really for the end user. It's for modpack or mod developers

Yeah, I'd rather not have a config screen so that people can't easily change the credits.
