Markdown stays. Syntax steps aside.

Edit headings, lists, tables, code, and diagrams directly. Switch to source mode whenever you need the raw text. Either way, you are always working with the same standard Markdown file.

While writing: Focus on your content like you would in any document
When needed: Inspect and maintain the Markdown source at any time
After saving: Keep it portable, versionable, and editable anywhere
