Please implement this. I also asked about this "Display rating of the files' metadata and add an option to sync mixxx-ratings with file metadata". I wondered whether changes to metadata of files would have the metadata get updated within mixxx but I noticed the metadata that can be set in KDE with dolphin right-clicking on files is not what is shown within mixxx, so this doesn't just apply to ratings.
Furthermore, at a later point a way to easily sync these ratings would be useful too: you could set the ratings (and other metadata, even cue points) while listening on your phone and then sync just the metadata by exporting and importing just a list of for example track-title:metadata (not the files themselves and it would work independently on where your tracks are stored as long as for example the filenames match).
