Generally speaking, it feels like there just aren't enough features for multilingual users on any major operating system. Fast virtual keyboard switching is nice on iOS, but basically everywhere else, it's hard as a bi- or trilingual user.

So many times do I want live subtitles in multiple languages, at least two, simultaneously. Or vision capabilities to view something without translating a whole block of a UI or a webpage so I can read through missing intermediate to advanced vocabulary or typically native turns of phrase.

Language support basically everywhere feels like it's implemented by Americans who can't speak anything else besides English, and look at products as things that only monolingual users use.

Single-layout physical keyboards, etc.

I'm curious, what's your use-case for this?
