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.
There are less bright and distracting backgrounds, which should make the site easier to read. Here are some screenshots from the default theme:
