Good idea, but too messy when consulting it. It needs a visual rework to make it more clear to use.
Also, this is cleary made with only Kanji in mind. British dictionary lacks of synonyms, antonyms and better explanations.
Good for a beginner, but not for who needs a better advanced user case.

loved it. however, PLEASE make it stop telling me "welcome to yomitan!" every single time i open firefox! would give 5 stars otherwise.
