A way to filter categories differently on searches.
How about being able to filter categories in an "all but" way. I think it would be particularly helpful when browsing auctions. You could search all auctions sorted by "ends soon" and filter it by "all but" USA(for example) then you could watch for auctions as they close, without having to wade through all the USA duplicates. Or look at all Europe "but" Switzerland. Or however you want. If there is already a way to do this, I'd like to know about it.
