I find that oftentimes with the flashcards on the website, the kanji can be quite hard to read with the font, and I find myself having to look them up quite frequently using other tools (or just copying them into another application). The font is big, so it should be easy to read, but I find that it is so bold that the features of a Kanji can get quite mashed together...
Maybe a choice of fonts for the flashcards?
Or even just a replacement of the current font?
Anybody else agree with me?
