To see it in action:
Crust.piefed.social (the Piefed development instance)
Not all instances implement it yet, I guess it depends how often they pull from the dev branch
Example of search for 'movies'
Cheers, yes I already tried all the themes they mostly change the colors and fonts tho. A little padding at best. Maybe someone created a custom CSS for it, which you can apply right under the themes section. But I haven't found anything yet.
