How about adding shadows for the text on toolbar, windows bars and menus? Nothing fancy, just the same text with different color under the "normal" one, and displaced by 1px V&H. Maybe some resources describing the color of the shadow and maybe the displacement distance in the menu files? If someone doesn't like the shadow they can use "sameasparent" or whatever that transparent attribute was.
I've tempered with an actual screenshot and manually added some shadows to see what it would look like. It's pretty cool, and I'm surprised nobody thought of this before. Of course, there may be other difficulties I'm not aware of. See the shadows screenshot at: http://xlife.zuavra.net/spirit/bbxp-shadow.png Ciprian Popovici
