Thank you for bringing this up! I didn’t include it because the average student will already be overwhelmed, and I couldn’t think of a good example s of when the kinship maps would be useful for students that don’t already know a lot about Chinese characters (and those students will probably notice this feature anyway). The sheer number of variants and the somewhat tricky interface makes it impenetrable for many, I think. Do you have a good example where this is genuinely useful without also being potentially very confusing? With a good example, it would be easier both to show how it works and why the feature can be useful!
