A production is not a folder — it is the record the gear list, the call sheet, the quote, the invoice and the releases all read from. Enter the dates once and every document knows them. The board opens with what is blocked, not with a list you have to read.

The panel across the top pools every blocker on every job into one line each — 2 invoices overdue, 1 quote declined, 3 call sheets not sent, 4 jobs with gear still to pack — with the total and how many jobs it spans.
Jobs sit in date buckets rather than one long list — shooting today, tomorrow, next 7 days, next 30, later, no date yet, wrapping up, completed, archived. Empty buckets are not drawn.

The dates you set on the job are the dates the call sheet prints, the days the gear is booked out for, and the days the quote prices. Change them in one place.
Anywhere: an enquiry, a quote, a calendar hold, or an invoice you raised somewhere else. Create Production can build the job from any of them rather than making you start with an empty form.
No. Mark one not required and its track draws a dash and its chip is struck through — the completion bar stops counting it.
It moves to wrapping up while anything is outstanding, then completed, then archived. Archived jobs stay searchable and keep their documents.
Yes. The company switcher is a filter that applies to the board, the calendar, documents and most reports, and each company carries its own branding, numbering and billing currency.
The sandbox has productions at every stage — one blocked, one shooting, one waiting on payment. Nothing to install.
