Feature request: functionality to auto-hide articles from a user-configurable domain kill-list, for those of us who don't want to see articles from e.g. Politico or Buzzfeed. Bonus points if it could also filter stories with user-configurable keywords in the title.

I've suggested this in the past to dang for the main HN UI, but they have limited resources for this sort of thing and there's a fear that if filtering is too easy, it'll split the community here.
