Yes, that's something I'd like to have at one point. I'm open to contributions on this matter: https://github.com/omega-gg/MotionBox
I see. Unfortunate for us, I don't have this knowledge to help; can only hope that this comes someday.
I already watch videos in potplayer (I used vlc, as you can guess, in the past), as it supports youtube, but it lacks the "browser stuff", which I have to do with another application (a feed program), and streamlink for twitch, so, it's kinda automated, but still not perfect (semi-automatic, I guess?)- and I am probably the only person in the world that does something like that.
