I just pulled up the Safari browser for Windows and boy, howdy! it really is dark, and it seems to get progressively darker as you move deeper (read, downwards). I googled safari title bar contrast and noticed some interesting discussions on the topic -- it looks like it's become more of an issue with Safari-4.

anyways, is it possible to reposition the 'tab bar' to the top of the stack (as it were) to take advantage of the (seeming) gradient?
