The Dialogue Mode plugin enhances the writing experience in Obsidian by fading out non-dialogue text, helping users focus on dialogue sections. This feature is particularly useful for writing scripts, stories, or any text that emphasizes spoken interactions. Users can toggle Dialogue Mode via the command palette and adjust settings such as fade intensity and dialogue text color for a personalized experience. Advanced users can further customize the appearance using CSS variables. The plugin provides a simple yet effective tool for managing dialogue-centric writing tasks within Obsidian.
