The Serendipity plugin brings the concept of serendipitous discovery to Obsidian by displaying a random note from your vault each time you open the application. This feature encourages reflection on past notes, sparks nostalgia, and helps generate new ideas from old learnings. Users can customize the plugin to include or exclude specific directories, ensuring only relevant notes are surfaced. With a clean UI that adapts to your Obsidian theme and a direct link to open the displayed note, this plugin enhances your note exploration experience.
