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.
You are right about the colors being difficult to distinguish by some people, I liked it because it was clean, but now I think it shouldn’t be the default option if there can be a clearer one.
