The instructions for configuring columns talks about mapping statuses to columns, which makes perfect sense, except that there is nowhere on my screen to map statuses to any columns. When I set up this Kanban board, I was prompted to create a Kanban backlog. But now there is nothing in the To Do column, and my board only shows In Progress and Done. I want a to do column of the stories assigned to me, to be visible next to that In Progress Column.
