OmniOutliner

This is not your father’s outliner. It’s more of an organizational tool. Outlines? Yes. It also collects and organizes data, manages tasks, tracks expenses, plans events, even handles multiple columns.

Use OmniOutliner’s document structure to create hierarchies of main headings and subpoints that can be expanded and collapsed, which are immensely useful when it comes to brainstorming new ideas, drilling out specifics, and lining up steps needed to get everything done. But you aren’t limited to outlines – you’ve got multiple columns, smart checkboxes, customizable popup lists, and an über-innovative styles system at your disposal.
