Changelog

The fullscreen editor now lets you collapse either panel to reclaim space when you need it.

• Collapse the code editor panel to put the live preview in full view — great for reviewing final results
• Collapse the properties panel on the right for a distraction-free coding session
• Click the pill button on any splitter to toggle — drag the splitter to resize freely otherwise

You can now open any block in a dedicated fullscreen editor — directly from the workspace preview. Click the pencil icon that appears on hover to launch the editor in a new tab.

The editor gives you a split-panel view with your HTML and CSS code on the left and a live Shadow DOM preview on the right. Changes render instantly as you type — no manual refresh needed.

• Full-width code editor with syntax highlighting powered by CodeMirror 6
• Live preview isolated in Shadow DOM — your host page styles never interfere
• Properties panel on the right for metadata, version notes, and publish controls
