### 1. Is this request related to a challenge you're experiencing? Tell me about your story.

The current Markdown is not very user-friendly. I recommend using a Markdown editor, which is also in the React version. Experienced users can give it a try. If you think it's good, I hope you can add this Markdown editor，thinks: https://github.com/imzbf/md-editor-rt
