I know the developers are working hard and I’m sure they’ll be coming with Mlem updates. I hope to see a notification centre being added, as well as the posts being collapsed instead of full-length. Do you wish for an Apollo type of design, or similar?
Edit: just a heads-up, I am not in any way affiliated with LemmyNet nor its devs. You can also voice your suggestions via Testflight by beta-using Mlem.
Searching for communities is essential. Like others have said, lift as much inspiration from Apollo as possible and you’ll basically end up with everything users need.
