I see. It would be very useful indeed to see the pitch-accent on these other pages. I now installed the pitch accent userscript and it seems to work. I thought getting the accents on the item inspector was the extent of it.
You are right that it doesn’t work for the kana-only words btw. Hopefully that can be fixed by WK / the scripter.
Link to the pitch accent script for those who didn’t know of it (like me!)
