I find the list formatting where you have the ability to easily reference subheadings really useful in long lists. So you’d have top levels that are numbered followed by subheadings that use letters, roman numerals, etc. This is a pretty standard format in many programs for creating documents, such as Google Docs -
Here is their options for standard ordered lists:
In MD, my only option is to mix numbers with bullets. It’d be nice to have a way to allow other options.
On our platform we’re working on mixing rich text input with MD - we render everything into MD but people can copy and paste rich text into an editor in rich text mode and we’ll convert what we can. It’d be cool if the spec allowed for more options because it’d allow us to retain more of the formatting we receive from a rich text document.
