Here's a somewhat search-related idea I've thought would be useful (almost wanted to build it myself): searching for political news with different viewpoints.

For example, if I search "Trump ate a banana", then I get articles on that event from Democratic, Republican, and other points of view - possibly tagged as such. I've always felt that it's tough nowadays to get a clear view on things because it's easy to fall into an echo chamber and only see articles that a certain group supports.
