I compiled it on Linux with some small fixes, and I will do some small GUI arrangements. For example, hiding the native titlebar, adding buttons for closing and minimizing the application, adding a beautiful font for the GUI, etc.
On Windows, I am still working to compile it.
In short, all versions (Windows, Debian, Ubuntu, KDE Neon Linux and macOS) will seem very similar (with some native differences on preferences windows, but not on the player window).
