You are right but from your point of view, What I meant is when you hover over
a photo,  You can see the rating stars indicating the rating of this photo,

Can you differentiate between the (unrated) photo and the (0 rated) photo ? ,
No you can't.

That's what I mean by implementing the 0 rating, Even if it already exists in
some parts of the code, But the user can't feel it, unless he use the advanced
search window.

If we would implement this, I suggest adding another icon beside the rating
stars to (Un-rate) the photo, Of course we must ask the community about this.

There are some plans in my head dedicated to digiKam, But I'm waiting until I
finish my final exams.
