I dont even use youtube anymore, i just use freetube and select the content i wanna watch by myself. Private frontends are the best. No spyware or bloated webpages or anti-adblock. Freetube even has support for external media players like mpv and vlc and smplayer and others. It even has optional tor and invidious support. Sponsorblock and Dearrow support as well.
running in the background isnt a system tray. every other desktop on the face of the earth has a system tray. It’s a basic espected feature and i use system tray functionality all the time.
