Please consider using my theme on this instance, so that everyone could enjoy a more more modern, efficient UI when browsing sh.itjust.works. It works with Lemmy 0.17, 0.18 and 0.18.1rc. It has a light theme variant, dark theme or both (auto).

It’s also a Firefox addon: https://addons.mozilla.org/en-US/firefox/addon/lemmy-modern-ui-theme

The only downside would be maintenance. Whenever a new version of Lemmy breaks the theme, someone will have to fix it. But I believe that together as a community we can easily maintain our own theme.
