If you stare at dreamweaver for hours upon hours each day, as I do, the default color scheme with the white background can get hard on the eyes. In the past I tried change the background color to black to give my eyes a break, but the code colors were then hard to see so I ended up switching back.
That was until last weekend when I came across this dark code view for Dreamweaver. I've now installed it on three of my computers and I am really liking it. I recommend checking it out.
