I know. I meant something different. Like when a subtitle track would be labeled as English but it’s actually Dutch, or something similar to that situation.
Hmm, ok. Noted. 
DeepL is better in general, I think, for the languages it supports. But also pricey. We use Microsoft translate, which is decent and better value, and still about a third of income from subscriptions goes on machine translation API costs. We have something in the works though that may help.
P.S: Another idea, for starting to learn a new language from scratch using your extension, it would be pretty damn cool, if you could auto-mark (highlight) the first 1000 (up to 3000) most common words to the user, so he would know what to focus on and not get lost in the sea of it. I think you guys might have already implemented such or similar feature in one of your first releases, if i’m not mistaken.
I added the backend code for this feature over the last few days. We used to have this feature, it got taken out during a heavy refactor. So, the way it will work is you set your level in settings (1000, 2000, 3000 words etc.), and the program will color words above that level (that aren’t already saved) as… purple… for example. (We used to grey them out actually.) Maybe it could be a bit more smart, and would auto-adjust the level so that a certain percent of words are ‘white’ (‘suggested to learn’) for each video. Haven’t really though about it seriously yet, I’ll make a new thread for that discussion.
