great job Rated 4 out of 5 stars
Just installed it to read some texts of http://www.aozora.gr.jp.
It looks great, even the line-height remains balanced in the pages I looked at so far. It must have been rather difficult to get everything right. However, I hope that in the end ruby support will give more options to the user. For example the option to toggle between different kinds of display. Like furigana versus popup text - or at least the option to disable the function with one click, since it may not always be compatible with certain website layouts. And it is not compatible with the fixed size bitmap font I normally use to read Japanese. But with a TTF it looks, like I said, great. Thanks!
