Месячная сетка с дивидендами, купонами, амортизациями и погашениями по дням, выплаченными и ожидаемыми, с сводкой за месяц и списком выплат выбранного дня. Раскладка без прокрутки страницы: высота ячеек подстраивается под окно, на широком экране список справа. Прежний список остался вторым режимом.
