I think having the ability to copy the curl timeline output as HTML would be beneficial when using chat clients like Microsoft Teams. This feature would bring the color highlighting with it. If implemented it should probably be a preference.

I'm not actually sure how to implement this though but it seems like a good issue for a first-time contributor to tackle. Perhaps Codemirror (the text editor component we use) has an easy way to enable this.
