Proposed feature: Integration with KKLC (and other indexes)10 February 2017
Would you like to see additional kanji sequences supported besides RTK? For example KKLC (The Kodansha Kanji Learner's Course) or "RTK Lite" (community-designed list of the 1000 more common kanji from RTK).

This feature is in brainstorm phase, meaning any input as well as votes would help to move it forward. You can help by reviewing my implementation draft in Support additional kanji sequences such as KKLD or RTK Lite #70 with a simple Github account.
