I genuinely hate using YouTube because it's awful. Random pop-ups all over the page. Weird suggestions on the sidebar because I don't have an account and don't want one. Ads that start in the middle of a sentence and play again if you rewind, etc. so you can't actually understand the video you're watching. So I wrote an app that takes a YouTube URL, downloads the video with youtube-dl, and just plays it in a normal OS window. No web browser needed. No junk. It's awesome!
