I agree, I feel like the UI could be a tiny bit more clear, and old.reddit does exactly that.

For example, threads seem to lack a tiny bit of indenting, perhaps a tiny splash of bg-color alternating.

Another thing that I have an issue with, is the page auto-refreshing. That's something that really makes me press "ctrl w". I am reading something, it's there, and then it's gone. Nope.

One last thing, and this is particular to the Fediverse - When someone posts a Fediverse link (to lemmy sub on a different instance) and you end up on a the website of that instance, obviously not logged in. You have to copy the link to your instances search... You know what I mean, it just makes it all clunky. It would be nice if Lemmy could check if the link is from the Fediverse, and then offer the option of "opening it locally".
