To change the order of the Agile board columns, please change the order of the issue statuses. Let's take the look at the following example.
We have the following order of the columns - New, In Progress, Resolved.
So, now we go to Administration (on top) - Issues statuses. Here, we could see the same order, counted from top to bottom
Note: Please keep in mind that the Agile board columns are actually the issue statuses by their nature.
We change the order via the green arrow on the right - please drag and drop.
As a result, the order of the Agile board columns is being changed.
