The amount is the headline, notes come first at full width, then the last twelve visits to the same place as a dot timeline next to the paying account's days around it with the running balance. Fields edit in place: j and k move, Enter opens and saves, Esc cancels, s c, s b, s t and s s jump to classification. A matching subscription shows as a suggestion, L links it.
