Mastodon should have a way to see the language a post was written in, without pulling up the browser’s dev tools to do it.

Quick hack — user css that (mostly) works for my instance.

.status__content:hover .status__content__text[lang]::after {
content: "💬 " attr(lang);
position: absolute;
top: 0;
right: 0;
font-size: .8em;
opacity: .6;
}

.status__content:hover .status__content__text.translate[lang]::after {
top: auto;
bottom: 0;
}

as always, it depents on your app client.
In my case, I am able to see (👉English)

Fair. I use the web UI on both desktop and mobile, though 🙂

@dcoderlt also a filter by language
