Topic tags are no longer shown in listing pages by default (except
"important" ones such as "nsfw" and "spoiler"), and the layout and
emphasis on them has been adjusted in multiple other ways as well. A
preference to continue showing them in listings has been added, and this
preference is enabled by default for all users with the "topic.tag"
permission (ability to tag any users' topics).
Other changes:
* The tagging field is collapsed by default when posting a new topic. If
a user expands it and enters tags, it will be shown expanded in the
future. It will also be expanded by default after the user
adds/changes tags on a topic, and will also be set automatically for
users that have shown an interest in tagging recently (by submitting a
topic with tags or changing tags).
* "Content metadata" such as word count and duration is now shown next
to the group name (where tags were previously), instead of after the
title.
* Topic icons (favicons) are now shown next to the domain name, instead
of before the title. Blank icons no longer have a dashed border and
are now just an empty space.
* When on a topic's comments page, tags are now shown in the main
content area, below the "byline" information about who posted the
topic and when, instead of in the sidebar.
* Other minor layout changes to adjust for tags, as well as prepare for
some other upcoming changes like adding "actions" to topics in
listings.
