Double subtitles...
 

I sent an e-mail that was not answered, perhaps I may have more chance here :

You could allow to have two simultanated subtitles shown.

This would allow non-english speaking people to learn very well English.
In fact, to have one subtitle that match English above and
upon a translation in another language could help improving English
vocabulary (for instance, in movies, I understand what they say, but
sometimes a word is missing in my vocabulary, and it would be nice to have it
translated upon the movie, in another font for it to be discrete).

I think this could be a nice new feature and would not give you much
work (re-implementing another subtitle display, except for the delay
functions I suppose).

Thanks trying to make a real good player (the only one I think is good
actually).

Have a great day.

You already can have two subtitles (with external software)
 

Just use players subtitles for one language and mixer subtitles for the other (try "ffdshow" or "DivX G400" , they both can show subtitles)
Also ffdshow can be used as decoder and for postprocessing
