The Steam Workshop has been updated to add a Search functionality. And really, how could we launch without this? I blame Tom.
Also in this update:
Workshop is now a top-level menu item within the Community. When you are logged in, you can see it alongside “Profile,” “Games,” and “Friends” in the top menu bar
When using the category check-boxes, the page will reload after each selection. This will let you more quickly explore the categories of content and see your results narrow down as you select more terms
De-italicized comments. Who would design comments in all italics? Oh. Hello.
