I've been working on an alternate frontend that might fit your needs.

Here's a link to this post on the official instance

On lemmy? No. The devs decided to do a single page app with a REST API, which leads to the sluggishness and slow load-time. kbin (which is compatible with lemmy's content) is your best bet, IMHO. https://kbin.fediverse.observer/list

I'm too used to lemmy unfortunately, and kbin is far from perfect.

I actually would really like something like new Reddit, Lemmy is far too horizontally dense despite wasting tons of space on both sides. I can't actually tell which comment is the top most either.

Generally its just difficult to discern what exactly I'm seeing.

If I don't find something soon-ish I'll probably get deep into making my own restyle script.

already exists. https://old.lemmy.ca I was surprised to learn how many different front ends my instance already had. I'm not sure what it takes to get it integrated on your instance
