Formulas, formats and co-editing

Proposed interface concept Not released. A design for discussion, drawn in HTML and CSS; not a screenshot of working software.

The spreadsheet editor shows the work people do in Excel and Sheets: a SUMIFS formula pulling from another sheet, number formats with negatives in parentheses, totals that add up, another editor’s cursor and the sum of the selection in the status bar.
