[UX] Add a default Taxonomy (tag/category) layout

The default homepage design of most CMSs all look like the blog homepage (2 columns, header, recent posts in asc order & footer ) including the category page, the tags page, etc. It's like there is no thought going beyond this design pattern.

Sure, it fits for the blog but must this design pattern extend to the whole website?

I think the taxonomy/category/tag page needs it's own look.

Doesn't need to be radical. What if the category page listed posts with just its title. Is this great? Maybe. Maybe not. But, at least, one can visually tell when they're on the homepage, the blog, and the category/tag page.

Something like this.
