The Show Whitespace plugin enhances the readability of Obsidian notes by visualizing leading and trailing whitespace in both Source and Live Preview modes. It highlights spaces at the beginning and end of lines, blockquote markers, and whitespace in list markers (e.g., bullets or numbers). Users can customize the appearance of these visualizations via built-in settings or by defining their own CSS styles. The plugin ensures that formatting inconsistencies in notes are easily noticeable, improving clarity during editing. Additional options allow users to toggle specific whitespace visualization features for a tailored experience.
