I would like an option to show and also filter on Image Rating (Exif tag 0x4746 18246).
It's supported by Lightroom and Windows.

Some new cameras also let the user set Ratings on the Camera, but unfortunately this is stored as proprietary MakerNotes usually not supported by 3-rd party programs.

Example: FujiFilm tag 0x1431; Sony tag 0x2002

Do more of you want this feature?
