Display the Tag Cloud or the Archive directly in posts and pages, and change their look in the options.
Tag clouds and Archives are useful for visitors, but also for search engines to find and index what topics your blog relates to. "Post Tags and Archives" makes it easy to add Tag Clouds or Archives to posts and pages via shortcodes. Before, you could only put it in the sidebar or widgets. That could hurt the search ranking for relevant terms and crowds the sidebar. So one either had to truncate the cloud and archive - or get rid of them (or use some more complicated trickery). Now you can just drop them in your posts and change the look easily via the options.
