Description

As initiated in #4393 I propose allowing users to display post tags on the index pages.

Use Cases

Allowing users to navigate to the relevant topics by following the tags visible on the index page

Screenshots / Mockups

A coarse example shows tags being displayed after the post date info. I didn't add tag's visual styling, but this is mere because I don't know how to do this quickly.
