I recall using an app/service/... for offline access to all kinds of docs, but sadly, I don't remember its name. (I know I have used it to access cppreference and such). Any ideas? 🥺
Alternatively, any suggestions for offline access to JavaScript docs? MDN says it has offline access but then says it's only for "MDN Plus", which it also says I have but does not provide a means to enable offline storage. 😤
