Is something like this even possible?
As an example, I’m looking for something akin to newpipe for youtube. I’m not really looking for something that collects all of my games into one location (that is a nice feature though). I’m looking for something that improves the user experience in the form of better user interface, etc.
I do a lot of browsing on the steam store page, but it sucks that you either have to watch the videos full screen, or default. No resizing options. Margins are too big too, it feels like it was designed for mobile or something.
I would very much recommend Playnite, a centralized launcher for games on all kinds of launchers.
You basically enable plugins for shops like GOG, Steam or whatever, it scans all games and then you got a central interface. It automatically launches say Steam, then the game, and on exit closes steam again.
Playnite is all you need OP. Afaik there is no alt UI for the media unless you use a browser.
