HN could really use some client software. If nothing else for choosing how to read thread replies (ie: most recent, most upvoted/popular, most downvoted, by replies from the OP, etc) + a more advanced built in search.
I have been to the settings, but it's a good example of why defaults matter and on-screen really helps people.
And extra crazy with "typo-tolerance" ON, "optimized" and "optimised" are very different results. Which is technically true, that is not a typo, that's grammatical.
Filter by author is important as people use that to search their own stuff.
