Grayjay is a cutting-edge app that serves as a video player and source aggregator. It allows you to stream and organize videos from various sources, providing a unified platform for your entertainment needs.
It's mostly used as a YouTube frontend^. However, it is now launching as a desktop app for Linux, Mac and Windows.
Lots of desktop front ends.
Meanwhile I got to emulate Android to run S-Tube because there's nothing good for remote control use for Plasma Bigscreen.
At least my Bigscreen "easy to use" legit package might be done soon.
