The 5 Paths and 9 Vars can easily be moved around by dragging and dropping the 1-5 and 1-9 buttons.

For example, to swap the listbox Path1 and listbox Path2, click on the #1 or #2 button, drag the mouse to the other button and release the mouse.

To insert an empty listbox, drag an empty number button (dark gray), when you release the mouse, an empty listbox will appear. Other listbox contents will move to the right to make room for the inserted listbox.
