As for the notebook credits — we know there are a lot of cases where this doesn’t work (e.g., a behind-the-scenes notebook generating many embeds where the title has nothing to do with the content being shown), and want to explore more options; for now the Iframe’s priority is just to be a zero-configuration default.
