Quartz supports adding titles and line highlighting to code blocks, but the format is slightly different.

• Implement a small preprocessing step in Quartz Syncer.

  • Convert line numbers
  • Convert highlights
  • Implement format check
• Check if Obsidian provides a way to check if a specific plugin is installed and enabled.
