I found the scroll bars very frustrating. They are so small that I could not drag the bar around very easily (reminds me of default scroll bars in Ubuntu these days). The contrast is so bad between the part that is dragged and its background that it took me a few seconds to actually make out which is which. The contrast of some of the text being grey on a darker grey background in the right sidebar was hard on my eyes. That part wasn't as annoying to me as the scroll bars though.

I do like the idea of this. The functionality seems to be there.
