Make the first file.
You do not need a new idea. Package a worksheet you already run, the notes behind a free tool, or a template for a chore you repeat. The shelf starts with one of each. They are starters, saved on this browser.
Worksheet
Shift Ledger
Four numbers off a stub, then the value of a day.
Notes behind a tool
Bench Runtime
Give the calculator away. Sell the caveats.
Template
Counter Cards
A blank that is faster than starting over.
