One could also open an Issue in GitHub. You can tag it as an enhancement or bug. There’s quite a long backlog now but at least good ideas will be documented. Either the devs will eventually make their way to it or some developer will see it and implement it.
I doubt the few guys working on Lemmy have time to add new features. Especially with another surge of users coming in hours.
But if you can find someone else who isn’t occupied, you can find the source here. https://github.com/LemmyNet/lemmy
Just fork it and create a pull request explaining what you’ve done. (Or what you’ve gotten another developer to do.)
