We cannot remove the default columns of rank and product value from the prioritisation view even though we do not use them
People are confused by what the rank means and why the numbers dont align with the order in which items are shown on the page. The product value column takes up real-estate on the page and is not useful as it is all 0.
Make Rank and Product Value columns that can be deleted. Allow the prioritisation to be done simply based on the drag and drop order of items on the page, with the priority line as an indicator of what is/isnt the most important at any given time for the team.
