Optional ReadonlyaboutExtra rows for the About dialog, after the package's own.
Optional ReadonlyauthorWhose name goes on a suggestion while track changes is on.
Optional ReadonlycontentThe document to open with. Defaults to the tour of every block type.
ReadonlyelementThe element to build into. It is emptied first, so give the editor one of its own rather than a box that already holds something.
Optional ReadonlyheadingThe page heading. Plain text; pass null for no heading at all.
Optional ReadonlymaxRefuse an image larger than this, in bytes. Default 5 MB.
Optional ReadonlynamespaceThe prefix under which preferences, the autosave draft, its backups and
the document workspace are kept in localStorage. Give two editors on one
origin two namespaces and neither reads the other's drafts; give them the
same one and they share, which is sometimes the point.
Optional ReadonlyonCalled after every change, once the readouts have been refreshed.
Optional ReadonlyparagraphsParagraphs under the heading, each an HTML string so it can carry
<code> and <strong>. It is written into the page as markup, so pass
copy you control, never anything a reader typed.
Optional ReadonlyplaceholderThe grey text in an empty document.
Optional ReadonlyserializedHeading over that readout.
Optional ReadonlyshowThe readout that shows the HTML a download would produce. Default true.
Optional ReadonlyuploadWhere dropped images and attachments are POSTed. The upload falls back to a data URL when the endpoint is missing or refuses, so a build with no server still works; pass null to skip the request and go straight to the data URL.
Copy for the header this layout puts above the editor.
