Hello, thank you for this awesome efficient downloader ! 💯 🥇

Please i have request : for exemple we hope to download quuckly only audio from youtube videos poscasts, so it will be great to even more speed up and simplify the process of adding presets worstaudio, bestaudio, worstvideo, bestvideo, option to download directly quick medium video resolution, -f worstaudio -x, -f bestaudio -x, and adding cookies preset if there is problem with dwnloading video from facebook for example.....: --cookies-from-browser firefox....

Thank you so much !

Thank you for the suggestions. I do have the cookies option as a custom preset myself, as I ended up not including it as a builtin preset due to the need of hardcoding the browser name. I'll look into it again after fixing #177 and see if we can have more useful builtin presets.
