Here is a quick trick to write Markdown or any text related format in VSCode comfortably and without messing with your file line endings: soft line wrap.
By default, soft line wrap will happen at the end of the editor. With this setting, it can happen after the Nth character:

1. Open user settings in JSON format
2. Add the following lines (replace Markdown by your file format, e.g. (gemini):

"[markdown]": {
  "editor.wordWrap": "wordWrapColumn",
  "editor.wordWrapColumn": 100,
}

3. In your Markdown file hit ALT+Z to toggle line wrapping

And voilà! It's way more comfortable to write.
