The thing i want for this is a video downloader, you click it and there will be a textbox where you will put the link of the video you want to download, the difference is that there you can put a video from more websites than Youtube like Twitter, Reddit or Facebook, and you can download them with the resolution you want, i think it would be useful because you will get the videos you want to send to a friend or to video editing without searching a lot (Sorry if this isn't very understandable, i'm not good in english)
