Let's say you're creating a blog or portfolio and you've got several categories (fashion, art, advertising, portraits, etc.). You want to create a "category" (collection) page so that someone can click "Fashion" and see all the fashion posts. However, for whatever reason, you want the "Advertising" category page to have a unique layout. Currently you cannot do this without using a 301 redirect or some other kind of hack.
