The Smart Random Note plugin enhances the functionality of Obsidian's built-in random note feature, allowing users to open random notes with greater control. With four commands available, users can open a random note from search results, insert a link to a random note at the cursor position, or open a random note tagged with a specific tag. The plugin also offers settings for customizing its behavior, such as opening the random note in the active leaf or a new leaf. Overall, this plugin provides a more flexible and powerful way to discover and explore notes in Obsidian.
