I really like this feature, but there is one thing I would like it to have: the capability to choose to make the toolbar, tabs and address bar transparent. On my screen when I add a custom background image I only see about a half-inch of it because the toolbar, search/address bar and tabs have to be a color which covers up most of the image. I would like to be able to make them all transparent as people do with custom themes, or better yet to adjust the percentage of transparency when choosing a color to make it even more customizable.
