New: Collapsible Sections

You can now add collapsible sections to organize long docs and make them easier to scan.

• Collapse or expand sections anywhere in your doc
• Headers stay visible even when content is hidden
• Works with all block types — text, lists, images, tables, sketches
• Collapsed by default on refresh to keep things neat

Improved markdown imports

Markdown imports are now more robust and accurate, with support for:

• Mermaid diagrams
• Anchor links
• Hints and block quotes

Burger icon when sidebar is closed

When the sidebar is collapsed, a burger icon now appears to make reopening it easier.
