I am pretty new to issues, so that's what the spam up there is.

What I mean by this is; I have looked at all the PHP files, (although I am bad at it) I still got the idea of it. I don't want all of the links like This person did here (https://github.com/Athlon1600/youtube-downloader/issues/73)[url] I just set the quality to find the best mp4 file, I duped your repo at https://youtube-downloader4.herokuapp.com/ just to on adding better css lol.
