On Pages in Store, each page now has a grip to drag it into order, beside its Up and Down buttons. Dragging did not work before.
When you write a page, Enter now starts a new line instead of saving, so Markdown paragraphs can be typed. Press Ctrl+Enter (Cmd+Enter on a Mac) or click away to save. The text then shows as it reads in your Store, with its headings, lists and links.
