A tip if you're used to old reddit and use desktop, check out old.lemmy.world. It as a dark mode like reddit enhancement suite adds to old reddit, and everything is exactly where I expect it to be based on my reddit experience. Since you're already using a lemmy.world account, it'll just work for you straight away.

Oh and also, you'll see that you can list things as "all," "local," or "subscribed." You can pretty much ignore local, and use all or subscribed as your main page.
