For tools like the Regression or Maxdiff, in menus where you select multiple variables, if a user wants to reorder the variables, either for aesthetic purposes, or because the order of the variables is important in the analysis, it is hard and jumpy to reorder the variables. While you can drag and drop the variables to reorder them, the window is small and the list will jump quickly when dragging and dropping. In very large lists of variables, this will be very hard to work with. A better version of the menu would allow the box to expand or for the dragging process to have a sort of acceleration to it rather than jumping quickly.
