Comments — every threaded comment on the active sheet, in cell order, each as a
CommentCard.
Remarks
Clicking a card selects its cell, and selecting a cell scrolls to its card and marks it. A new
comment is a draft card on the selected cell that writes nothing until it is posted. Notes are
not listed: a note is edited in its box on the sheet.
