One column, one set of numbers. A Worksheet is the quickest way to put together a cost estimate or a small budget, with nothing extra to set up. When that number starts to matter to a bigger decision, carry it straight into a Plan or a Decision Map.
Included on every plan, from Students & Thinkers up.
Keep a simple running list — a budget, an estimate, or a tracker — in one tidy column. There is no nesting and no branching to think about, so it stays as quick to use as it looks. When a list outgrows one column, a Plan picks up where a Worksheet leaves off.
