On: VLC 3.0 Media Player release

[Garvey]

Not sure about Mac but there's an option for that in the windows version at least.

Tools -> Preferences -> Playlist and Instances

"Allow only one instance" and "Use only one instance when started from file manager", uncheck both to allow more than one window at a time all the time.

Yeh that doesn't exist under MacOS.
