  ;; disable-account-indent? - a boolean to disable narrow-cell indenting, and render account full-name instead
  ;; disable-amount-indent? - a bool to disable amount indenting (only for single data column reports)
  ;; negate-amounts?    - a boolean to negate amounts. useful for e.g. income-type accounts.
