Leads → Pipeline.
One column per quote status: Received, Quoted, Approved, Confirmed, In production, Completed (Cancelled is hidden by default). Each card shows the quote number, company or contact, quantity, a preview thumbnail and the creation date. Click a card to open the quote.
A card doesn't move / snaps back. The target status is not allowed (nothing can leave Cancelled), or your role can't change statuses. Check the toast message.
The board is slow with hundreds of quotes. Hide Completed and Cancelled columns; the list view with filters is better for history.
