If we could end up with a theme that looks a lot more like kbin.social, I’d be so happy. My biggest gripe with Lemmy is all of the white space, and none of the current themes improve that at all. All of the theme options offered by kbin look amazing by comparison, and to my understanding Lemmy theming is done via CSS based on Bootstrap v4, so new theme creation should be straightforward enough.
It’s to the point where, when visiting Lemmy instances, I use a custom CSS extension to modify a few properties to make it a bit more palatable to me.
If you guys ever need help creating custom themes to offer to users I’d be happy to contribute.
