Neat! Any plans to make the different video qualities quickly available? Maybe as a subdir named with the resolution, eg search/movie/480p.mp4 or maybe movie.1080p.mp4?
Oh, I don't want to clutter it too much, it's better to keep it simple.
It definitely needs a mount option to set the default quality. Changing it later might be tricky, maybe passing options in directory names would be a good idea? for example: mkdir "foobar [q:720p]"
