Actually would love to tune the ranking of search as it is biased towards ancient stuff and I always need to switch to sort by date to find the article I actually vaguely recalled seeing recently. In Elasticsearch I would probably add some function scoring on dates, points, and number of comments. Also comment search is indeed not really a thing currently and there are some nice opportunities to find related stories, likely duplicates, etc. that might help people when posting new stories.

IMHO the default HN ui has many quite obvious UX issues on mobile with e.g. tiny click targets that are positioned close together, long threads that are hard to navigate, low contrast colors (grey on grey), etc. It's clearly not been designed with mobile in mind and even on desktop it's not all that good. Brutalist/retro is the best you can say about it and that looks like it's intentional to me.

If you read HN on the way to work in an area that doesn't have great mobile coverage in e.g. subway tunnels, etc. offline support would be pretty nice.

There are various Android clients that do some interesting things with the UX (e.g. thread navigation, swipe to upvote, etc.) and offline usage. However, most of them fall a bit short when it comes to things like commenting or other features. Most of the clients I tried did not cover all the features.
