For icons I’m using Iconify; a library of icon libraries :)
import Icon from '@iconify/svelte';
...
<Icon icon="mdi:filter" class="size-10" />
In this case im using the material design icons (mdi), but there’s many more to choose from;
Search icons (top right search bar!);

A similar library (for React/vue) is fontawesome.
