The Notes toolbar adds Strikethrough, Numbered list, Link (the same Link drawer as Documents) and Insert separator, in both views. Pasting into the Formatted view keeps headings, lists, links, bold and italic instead of pasting plain text. Heading and Subheading change a heading of the other level instead of adding a second marker.
