Checklists are now somewhere to work, not just something to read. • Notes: hover any checklist item and add a note. It saves into the file as a plain indented bullet, so every other Markdown tool still reads it. • Attachments (Mac): drag a file onto a checklist item to attach it. Click the chip to open that file again. • Clickable file references (Mac): a path written in a code span opens in your editor. • Path bar (Mac): copy the document's path, or reveal it in the Finder. • Live reload is steadier. iPhone and iPad also gain the interactive checkboxes and notes that the Mac version has had.
