In my current project i have to emphasize the submenu of one menubutton. So it would come in handy if you could apply a own, seperate set of style parameters, at least colors and maybe font, to the submenus of each Button. (as parameter input menu Button Buttonstyle Menustyle Misc suggest on the first view).
I therefore suggest a checkbox "separate Style for this Submenu" which is by default unchecked so all behaves like used. But if checked for this particular submenu a privat style is generated.
