It is the first acceptable theme that I have seen so far. Just use a litte less aggressive color for disabled versions of back and forward button, remove the green hover color on Tabs and increase the Tab height a litte bit, just few pixels and it is perfect! Good job!
I really love this theme,one of the best iv'e seen and used, Could i make one observation though,and that is that the icons are a little too big when used on a netbook 10'' screen,is there anyway to decrease the icon size,
I love this theme, best one I've seen in a quite a while, neat, clean, uncluttered. The icon size is perfect, one thing would make it perfect, that being support for personas, otherwise will be a favourite of mine.
