Please:
Re Google Drive and metadata, those are likely shortcomings of Google Drive, which has a very incomplete (and buggy) filesystem implementation. Cloud storage in general also will not sync NTFS ADS metadata, so applying ratings to files/folders under cloud storage will only affect the local copies, at best (except for formats where the ratings can be added inside the files, e.g. JPG has a way to store ratings so it's stored in the file instead of next to the file as NTFS ADS metadata).
