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.
I would like to see photo downloading implemented into the android client (the button is there as of now but it won’t let me download)
You have to talk to the authors of the client you’re using, because Lemmy doesn’t have an official client.
