The Pia viewer plugin adds custom typefaces to Obsidian, specifically designed for use with Munpia and Novelpia formats. It allows users to easily switch between these two styles, enhancing the visual presentation of notes. The plugin is adaptable, with the possibility of adding more formats upon request. It’s ideal for users who want to display content in a style tailored to these specific formats, improving readability and aesthetic appeal. While it currently supports only these two styles, further customization options may be available based on user feedback.
