Improve Access to Features

[squld]

Proposal

Markdown Copilot has many features, but it faces the following issues:

• Users cannot fully grasp all the features.
• Beginner users who are not familiar with keyboard shortcuts or the command palette cannot access the features.
• Users cannot access help or documentation within the editor.

Therefore, we propose displaying a clickable list of commands and descriptions in the editor, similar to Empty: Hint.
