I suppose that I will not be the only one who download series and then watch them quietly without ads and in high definition (if possible), but I also think that I will not be the only one who renames them to have them ordered.
Scenery allows us to rename series chapters taking the metadata from the Internet to achieve short but correct file names, that allow us to order by seasons for a comfortable disposition of them.
It's free and they accept donations, so if you use it… give them a hand.
