Thank you very much for adding Template:Ruby and incorporating it into the chapter pages! We really like the new format and would like to push the change to more pages. At the moment, we have a concern of the code being too convoluted by repeatedly calling the Ruby template for each Kanji character. It would work fine for short titles but for longer one like "変人・妖怪・魑魅魍魎", it is quite troublesome to call the template for every single character.
We are currently discussing how to best incorpate the Ruby template with the Translation template so that it's both intuitive and easy to use. Here is our discussion thread. You are welcome to join in and offer advice anytime!
