When acoustid-fingerprinter is started, it starts at $HOME (in folder selection tree).
It would be better if it could save a default-path in config for where to start falling back to $HOME.
Same could also be overridden if started from command line shell argv[1]. So starting it as acoustid-fingerprinter would automatically select that path in selection tree falling back to default path if there is any problem (folder does not exist, etc.)
