One that I’d like to see is a more in-depth sorting option for posts (allowing you to see for example top of December 2020, or top of a specific day). A custom date range selection would be best. I remember this being a frequently requested feature in the early days of reddit, and they never implemented it.
When I login it always brings me back to https://lemmy.ml/ Expected behaviour = bring me back to where I was, in the community I was before login in.
