The Discordian Theme plugin enhances the Discordian Theme in Obsidian by providing customizable settings directly within the app. It includes features such as Writer Mode, Flat Andy Mode, and Paragraph Focus with adjustable fade-out. Users can also modify readable line length, toggle dark note headers, and adjust font sizes for notes and the File Explorer. While the plugin is not mandatory for using the Discordian Theme, it significantly improves personalization and usability for those seeking a tailored aesthetic and functional experience.
