Related: I should be able to paste markdown-formatted text and have it automatically converted to the appropriate document styling. e.g. copying the following and pasting it into a Proton doc should not paste it literally with the # characters, but instead convert the first line to the “title” style and the second line to the “heading 1” style.

```
# Document

## Sub-heading

An introduction.
```

This is essential for writing documents quickly, and also for technical writers who want to collaborate. There should be a wysiwyg mode and a markdown mode for docs

Definitely a great idea! Online Markdown support would be great and, after all, "casual" users aren't forced to use it.

That's said, I think it would be a good way to attract developers and techy people :D

I love the new Doc support in Drive. However, I don't like that opening a markdown file creates a new Doc file. (For example, hello_world.md when opened in Docs creates a new file called hello_world, which results in me having two copies to maintain of the same file).

I think a simple solution could be to allow an option for "Edit as Markdown in Docs" or something.

Markdown would be super. Especially as it looks like the new document implementation is using it behind the scene. (you can download markdown file)
It should be fairly easy to add a "edit source" button in the toolbar.

This is the *biggest* thing that I miss switching from Skiff to Proton -- I exported and uploaded the MD files from Skiff Drive, but in-line editing was super-useful and IMHO is a good 80-20 solution vs. something heavyweight like Notion

Totally agree. Markdown support + some basic Notion-like structure for Notes creation and organising. I'd love to be able to share a link to my Drive with anyone where they can simply open the document directly, without a need to download it.
