History, copies and comparing calculations
How to return to an earlier calculation, copy it and compare two options.
Every run is saved automatically — you do not need to press anything.
View an earlier calculation
The “History” button shows recent runs. “Open” shows the result of that run; the form on screen does not change.
Copy a calculation
The “Copy” button next to a calculation creates a duplicate: handy for a new shipment of the same goods.
Compare two options
Tick two entries — “before” and “after” — and click “Compare”. You will see a table: what changed in the inputs and how much the money changed.
Autosave
Once a minute the draft form is saved by itself. Closed the browser by accident? Everything is there when you come back.
