I agree. In the beginning I was unsure about separating the two, but
having experimented a bit with my patches, has led to several uses
where separation is an clear advantage. For instance, having multiple
preprocessed versions of a photo does not mean that only one of them
is interesting.

Actually, I've tried to implement a "show hidden images" menu-item,
but it seemed to be a bit more work than I was ready to do at the time
:-). Some of the more knowledgeable will know if this can be done
easily or not.

This makes me think of introducing "views". A view would basically be
a search-expression of tags to show, and tags not to show. I don't
know if negations are currently implemented, can anyone clarify this?
Different people could then have different views. And one could even
have different views for different occasions.

On the other hand, this approach might be severe overkill, and in that
case it will complicate usage of KPA quite a lot. Right now, I
actually cannot come up with enough use-cases for this to be useful,
but maybe someone else can :-)
