You can fully customize your worklist or invoice view. By clicking on 'Columns', you can decide which columns you want to see. Simply enable or disable the columns by checking or unchecking them. Moreover, you can change the order of the columns by dragging them to the desired position with your mouse. Here you can use the icon (six dots, it is shaded yellow in the image below.)
Remember to click "Save" at the bottom of the list to save your settings.
