I was wondering if it would be possible to display which kanji list (jōyō, jinmeiyō, or hyōgai) a kanji belongs to in the kanji dictionary (search)? Maybe under parts? I don't know how the dictionary pulls its' entries on here, but the information is embedded in other popular online Japanese dictionaries (jisho etc.):
It would not be too hard to get in there - this might be a good fit once I (later this year, hopefully) get an additional layer of kanji data into renshuu :)
