Editor and live preview

The World Note editor comes with live preview by default, rendering markdown syntax visually. Headings, bold, italic, lists, and quotes render as styled text while you write, and the raw markdown is revealed when your cursor enters them. Tables, code blocks, and images render as widgets.

Formatting

Use the format toolbar and the right-click menu for bold, italic, headings, lists, quotes, and links.

On top of the common markdown styles used in tools such as Obsidian and GitHub (tables, task lists, strikethrough), the editor supports ==highlight==, #tags, callouts (> [!note]), footnotes [^1], and collapsible blocks (<details>). Task-list boxes toggle on click, and headings can be folded.

Footnotes

Write [^1] in the body and add a [^1]: text line near the bottom of the document to make a footnote. References render as superscript numbers, and clicking one jumps to its definition. Clicking the number on the definition jumps back to the first reference, and hovering over a reference previews the definition text.

The legendary sword Aurelis[^1] was found in the northern mountains.

[^1]: Believed to have been forged in the Third Dynasty.

Collapsible blocks

Use the <details> and <summary> tags to create a collapsible section. Put the opening and closing tags on their own lines and the summary line renders as a heading; clicking it folds and unfolds the body.

<details>
<summary>Spoiler</summary>

This content can be folded away.

</details>

Images

Paste or drop an image and it is attached to the project automatically. Both standard ![alt](path) and Obsidian embeds ![[name|size]] render, and local and relative paths are resolved within the project.

Where attached images are saved is set in the General tab of Settings.
