If I've sorted my tickets and I have some that are tagged and therefore 'categorised' to another view, I'd like to have a view without them. Makes it easier to progressively work through things. Eg I have an 'AWA View' and once a ticket is tagged 'AWA' I'd like it removed from my main view. I think this concept could then be used across all views. Include 'this' tag but exclude 'that' tag.
