    I'll try to explain. How menu system for GUI-based application may be
created? By another structure that will copy config but with some tree?
You may be very surprised but level 0 config already has all for GUI menu
in it. Only thing it has not yet was formatting field (from main menu
panel to drop-down menu, from drop-down menu to submenu, for separators
between parts of drop-down menu, etc.). So that CONF_TYPE_GROUP at first
was proposed as such formatting field (application-level type config
item). Finally on "Alt" keypress or mouse event we can just run some
function of GUI like display_menu(window,config) - it's enough and you
don't have to make some deep changes to reformat menu - just reorder
items of config in source or even in runtime. :)
    Did you understand now?

    With best wishes.
    Andriy.
