Having some issues with it, but might be my error ;) The pip-installed (in a venv) version will complain about missing data/theme.json, and then crash. So then I did the git-clone, pip-install variant, that starts. Interface is very minimal. After pointing it to my sshfs mount (~/mnt/Audio), it will list directories, but won't find a single file, strange.
Copy the an directory of audiofiles to /tmp, browse there, it works. Very strange.
