Although I'm not really satisfied with the previous comment's tone, I second the notion for using a separate font for the kanji lookup display. I don't know if it's intentional, but as soon as I have the Kanji Stroke Order Font (http://sites.google.com/site/nihilistorguk – shows small numbers next to the lines) installed, not only the big single kanji in the lookup display uses the font, the first lines in each result uses it as well. (See screenshot on – both kanji and hiragana use it). This makes kanji with lots of strokes unreadable even with the biggest font size.
When I have the Kanji Stroke Order Font (http://sites.google.com/site/nihilistorguk) installed, gwaei shows small numbers next to the lines in a kanji in the kanji lookup sidebar, which in itself is a very useful feature. However, the stroke order font is used for the first lines in each search result as well, which results in nigh unreadable kanji, even when using the biggest font size available (see attached screenshot).
In my opinion, the stroke order font should solely be used for the kanji lookup display.
