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.
Just as a side-note: Multireddits are not an Apollo feature, they are a part of Reddit itself since 2013. Although, Apollo did support them before the Redesign did (which calls them “Custom Feeds”) if I’m not mistaken.
