Updated with all three themes. Sorry for the image width...
I added saturation and contrast to the Stelz buttons for readability (I'm an old geezer), and made minor tweaks to a few of them. I love those buttons but I hate squinting. For the rest I just wanted to keep it simple and clear.
I use the medium version pretty much always now. The zip contains all three themes (and the icons, they all use the same icons).
