Ability to choose the quality by hand!

The downloader is easy to use and doesn't confuse, thanks for that! One integral feature that's presently missing is the ability to choose either a default quality or a way to change the quality for each video. Be it 1080p, 720p, 480p, 360p or even the smallest 240p/144p most likely to fit on the smallest of mobile screens, any of those quality settings should be available to choose from!
