The PMP app allowed to add a custom mpv configuration using a mpv.conf file located (on a Mac) in ~/Library/Application Support/Plex Media Player/
It was interesting to tweek parameters not available through the UI.
The same method does not seem to work with the new Plex app, so I have 2 questions:
1/ Is it possible in some other way?
2/ If not, can you consider adding it?
