Is it possible to obtain the text from the CreditSystem to apply it inside any widget, not just as default on screen?
That’s not a directly supported use-case, and I can’t say I’ve tried it, but it’s probably possible. I suggest taking a look at the source and deciding where you want to hook in to the credit system. Worst case you might need to modify the plugin itself, and we’d welcome a pull request with reasonable changes to improve the flexibility. You need to be aware of the legal requirements around attribution whenever you’re modifying the credits, of course.
