Hi, Parole is quiet fast but it lack of subtitle management. I could'nt load external subtitle (.srt) by hand. .srt are only recognize if they have the same name that the video. When you got a video with multiple audio track you could choose which one you want.
Switching between audio-tracks is already supported and choosing a subtitle file manually is around the corner.
Great news! Manual subtitle selection support is now available in the latest git master. Please test and report any bugs you uncover! :-)
As Sean said, it's in git master.
