I wish there were a more old-reddit style theme option for Lemmy.
Lemmy is certainly a lot faster than new reddit, but I prefer the aesthetic and speed of old.reddit.com and hackernews. I like the minimalism and how everything defaults to the left of the browser rather than the center. I also really enjoy how I can expand the entire text of a post without actually clicking on the post's link.
Just my thoughts. Hoping to see more theme and front-end options emerge over time.
In the meantime you can use custom themes with browser extensions like Stylus from [email protected] or injected scripts which try to recreate the old Reddit style.
