Hi there, I’ve been using myself the Chrome extension and it’s amazing how it detects the language automatically and checks for mistakes. I have configured 4 different languages (Catalan, Spanish, English and Polish), and in long texts, there’s no chance for mistakes because at the end, languages are different one from another, so the autodetect functionality work as a charm.
Anyway, it happened some days ago that I started translating apps using the Weblate service. There, strings to be translated consists on sentences from 1 to 4 words (average). In this scenario, the autodetect feature gets crazy and detects the text in the text field as a language that’s not the correct one (of example, the string being “Color”, it’s detected as an English word and strikes it in red because it suggests “Colour”; “Finestra” is detected as an English word and it suggests “Fenestra”; “Descarrega paquets de pinzells del wiki del programa” detects it as Spanish and marks 4 words in red; etc.).
So, I’m with @jaumeortola in this topic: it would be great to be able to set a preferred language choice in the LT Extension configuration, so you can enable it or disable it when you need to check the spelling of short sentences in only one language among a great number of webs (like translating platforms).
