Is an indented bulleted list an outline? In my head flat indented bulleted list that is produced via the opmlPackage as shown here is different than one that in which you can expand and collapse nodes as shown here. Each has a different use, but when I think of viewing an outline in a web browser I think of something that I can interact with and is not flat view. #

As an example, go to my tech outline and click Everyday Tech, Google Pixel 4a, Ongoing impressions, which I find to be a much better experience than if ever node in that outline was expanded by default. #
