Not GP but: would be nice to have a search engine that penalises content marketing and ad-heavy websites. The web is flooded with bad content, and Google doesn't seem to care, since it brings money to them. There's also too much duplicate junk: it would be nice to search for a song title and not being given 20 pages of copycat lyrics websites. Or 20 pages of copycat guitar tab websites. Also: software aggregators, Wikipedia mirrors, Stack Overflow mirrors, Github mirrors. I mean they're all the same, maybe just aggregate them together? Would also be nice to be able to filter out, or at least de-emphasise things like: piracy download sites, fake download sites, fake ebook sites. Of course that would need some curation.
