Maximize height of drop-down menus when there is enough room on screen

When I select an adjustment that consists of a menu, such as the “Rendering” option in the “Color Rendering” palette, the number of items in the list sometimes causes a scrollbar to appear, even when there is more than enough room on screen to display the entire list. For example, with FilmPack 5 installed, choose the Category “Color positive films” and then view the list of Rendering options. My request is to display the entire list of options without a scrollbar if there is enough room on screen.
