Check out Alexandrite! It’s an alternative Lemmy UI.
It supports many different instances (must be 0.18.1+, I believe) including lemmy.world and lemm.ee. I think it looks really good, it’s really smooth, and even has some nice features like live Markdown preview.
Yeah, it’s good. You may also want to try Photon, which is also really good and is in very quick development.
Oooh yes! It looks nice too. Thanks for the suggestion~
