What UX improvements would you make to Lemmy?

I've seen people suggesting improvements to sign-up which mostly amounts to hiding technical language (servers, instances, fediverse) and adding clearer signposts. I'm also seeing discussion on GitHub around UI improvements to the website as well as native apps.

Example: https://github.com/LemmyNet/lemmy-ui/issues/1183

What's stood out to you so far? Where are the quick wins to improve usability and accessibility?
