The Interactive Code Blocks plugin enables users to create and preview interactive code blocks directly within Obsidian. Designed primarily for drafting and testing these blocks, the plugin offers a simplified preview experience for code snippets written in Markdown. Users can visualize code marked as 'runnable' or 'editable' with various options such as runner and sandbox modes. However, the plugin is limited to basic functionality and does not replicate the full capabilities of production plugins like the Quartz plugin used at Windesheim for displaying interactive blocks. This makes it an effective tool for drafting and refining code during the writing process.
