first off congratulations and thanks very much for this incredible tool. used for 2 weeks and just had to get the lifetime deal. keep on the good work!

secondly, is there any plan to add trakt . tv integration to videostream?

If it's already implemented I don't think it's working.
I'm guessing that is only for internal subtitles?
I believe OP means downloading and applying subtitles from opensubtitle, etc.

btw, just got premium and it was the best purchase i made this year so far!
