I’ve heard many people saying that the front-end looks old and needs more work, but I’ve never heard someone describe how it could look better. To me, it looks perfectly fine. I wish it had a card layout similar to libreddit, but aside from that, I think it’s nice. If people want a completely different look, then there’s lemmyBB, and there will probably be other front-ends in the future. However, we should hear opinions about which styles people want.
For me, the primary issue now is it’s not clear how federation works. The UI now seems to be heavily inspired by traditional media (e.g. reddit, Twitter). But there’s not a whole lot of clarity when it comes to federation-specific features.
