This will be very helpful to me, as someone who is learning several of the supported languages. One piece of feedback: when I choose Cantonese, all I get is Mandarin results. I assume it's because the subtitles of almost all Cantonese videos are actually written in standard Chinese (with traditional characters). It would be pretty hard to distinguish between Mandarin and Cantonese based on subtitles alone, unless you parse the grammar of the sentences or look for Cantonese specific characters.
