so i have set to always use kanji for everything (set all kanji levels to 100% known), but in conjugation tables, kana is still used. I think option to use kanji in conjugation tables would be nice.
It's done that way since the focus on the conjugations is the spelling, and while it's just a few verbs, some (する。くる) have spelling changes "under" the kanji.
It might be something I can change in the future, but doubtful due to time restraints.
