Rated 5 out of 5 stars
What tru hh is said is SPOT ON. I love this theme with all my heart.
Also: Do you think you could update this for Firefox 4 compatibility?
Sure, I'll start working on a FF 4 version soon. Expect a version out for Firefox 4 a couple weeks after the launch of Firefox 4. Meanwhile check the development versions from the repository on the theme project website.
