In general it works, but each time opens new tab so after downloading series of video you get this blank tab polluting your tab line. Sometimes it does Not downloading high resolution videos 720,1080,1440p and 4k, as claimed leaving you blank tab that does nothing, so you have to redownload lower resolution video. And last but not least, the most frustrating is that it sometime opens a new tab with video wich suddenly deafens you on full volume and you have manually save the video from this tab changing its default name "videoplayback.mp4" every time. Would be nice to fix this issues an if it is managable - to give an option to download several chekmarked videos from playlist/searchlist/recomendations.
