Description Olivier Kes 2012-01-18 15:57:05 UTC 
Version:           2.5.0 (using KDE 4.7.4) 
OS:                Linux

I think we should change the checkboxes to three-states checkboxes (unchecked, selected, excluded), to allow finer filtering. We could filter all pictures having TAG0, not having TAG1, and indifferent to TAG2.

For example, if I want to see all my landscapes except those with sunset, I could filter by "+landscapes -sunset".

I was confronted today to the situation when I had to make a selection of pictures in my whole collecting by date. All pictures that were resized were shown twice, and I couldn't exclude only those.

Reproducible: Always

Steps to Reproduce:
.


Expected Results:  
Check boxes in tags filter should allow [ ], [x], [v].

Tags filter already supports this. You can set a tag to "exclude" mode either by middle click or via the context menu. At the bottom right, you can switch between AND and OR.
