I don’t know why this still isn’t obvious and standard in all places that use tags. Tags shouldn’t be only filter-to but also filter-out. Say there’s a tag for “beginner” okay fine, easy for beginners to see just that stuff. What about others deciding to hide all the beginner items? That’s much more sensible than requiring some anti-tag to be put on every single item other than those you want to hide.
There’s countless highly valuable use cases. Please: can this be made possible?
