Better yet, add a button to override user language options and show the chapters without having to edit the settings, reverting to hiding them if the user leaves the manga page.
Some people, like me, read primarily in English but can read in other languages if there's no choice. I keep a filter to show only English and not clutter my front page, but when I'm browsing a page of a specific manga with no English chapters, it would help me to quickly short-circuit my language bans for that manga only.
