Ah, no it does not do that

Like if you visit a link or go to someone’s profile, then go back to return to the comments, will your scroll position be remembered so you can see the comment you were just looking at? If so, yes

Mastodon has a pseudo-algorithm (sort of, unless there’s a better name) in the Search/Explore -> Posts view, which shows you posts that are trending on your instance. I wonder if Lemmy can come up with something similar based on your instance activity

You should consider switching to Megalodon. It’s a fork of the official Mastodon app so it’s already what you’re used to but adds features like following and pinning hashtags as we as supporting markdown in posts (if your instance is using glitch-soc)
