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.
Don’t get lost implementing fancy features at the beginning, concentrate on supporting what the Lemmy web UI does and try to provide a smooth and pleasant experience on iOS.
In case you’re looking for inspiration would highly recommend to take a look at the Ice Cubes client for Mastodon. An extremely well made app.
