We all need to put extension pretty much on hold for the reason that right 
now, we're just implementing R5, not adding to it unless it doesn't take much 
work and it doesn't break binary compatibility. However, don't think that 
brainstorming ideas is out of the question - we just can't put them into 
practice just yet.

There is some stuff already in R5 in InterfaceDefs.h:

enum color_which {
        B_PANEL_BACKGROUND_COLOR = 1,
        B_MENU_BACKGROUND_COLOR = 2,
        B_MENU_SELECTION_BACKGROUND_COLOR = 6,
        B_MENU_ITEM_TEXT_COLOR = 7,
        B_MENU_SELECTED_ITEM_TEXT_COLOR = 8,
        B_WINDOW_TAB_COLOR = 3,
        B_KEYBOARD_NAVIGATION_COLOR = 4,
        B_DESKTOP_COLOR = 5
};

_IMPEXP_BE rgb_color    ui_color(color_which which);
_IMPEXP_BE rgb_color    tint_color(rgb_color color, float tint);

Not sure what tint_color is, though. As for playing with system colors, if I 
have to support the ui_color function, you can bet I'll try to see if I can 
get away with something like:
set_ui_color(color_which which, rgb_color newcolor)
