One of the things I often used on Reddit was the ability to revisit my liked (or upvoted) posts. I used this as a way to later share things I found interesting or funny with people in the house. Is there a corollary on Lemmy? If so, I haven't found it yet.
I haven't found a history of upvotes and I think it's a great feature to add. Yes you can save posts, but I like to bookmark specific posts to share with my partner while still being able to upvote what I like+revisit them later.
