Yes, that's a recurring problem 😭
I think we should try a language filter in the top nav bar along other filters.
- dropdown menu : languages
- checkboxes with languages we chose + all
- link to language setting
I think giving the option to users to change their language directly in any pages would be better.
And we could expand it to no connected user, so they can find content related to their mother tongue.
And i would do the same for theming.
