Nice !
I managed to set this up even if it wasn’t intuitive (hiding the translations in the Exemples also hide them in the About section) but on every N5 item that I checked but one, the Caution and Fun fact section verbs are unaffected as you can see in は (JLPT N5) | Bunpro and な-Adjectives (JLPT N5) | Bunpro for instance.
Interestingly, the Fun fact section of る-Verb (Past) (JLPT N5) | Bunpro correcly hides the translations
The bad news is that the setting doesn’t “stick”. When I open a new tab, the translations appear again by default
