This plugin will convert every word that occurs in a post title or content into a term (tag). By default the plugin will add these terms to a new taxonomy called “words”. Optionally, the terms can be added to the “post_tags” taxonomy, used for normal tagging in WordPress.
The plugin provides the option to create a so-called stop list. Words in this list will be kept (or even removed) from the taxonomy. This allows authors to ignore meaningless, but often occuring, words like ‘a’ or ‘the’.
This plugin makes sure that the tags will actually cover a blog’s content. This is great in combination with tag-clouds as the tag-clouds will better show what the blog is about.

Right now WordPress currently presents no easy way for web publishers to add subtitles into their posts, pages, and other custom post types. This leaves users and developers in a bit of a quandary, trying to figure out how best to present subtitles in a beautiful and sensible way. Post <a href="https://codex.wordpress.org/Function_Reference/the_excerpt" rel="nofollow ugc">excerpts</a> are a very poor choice for subtitles and the only available option outside of <a href="https://codex.wordpress.org/Custom_Fields" rel="nofollow ugc">custom fields</a>, but custom fields aren’t entirely self-explanatory or user-friendly. This simple, straightforward plugin aims to solve this issue.
Simply download Subtitles, activate it, and begin adding subtitles into your posts and pages today. For more advanced usage of the plugin, please see the <a href="https://wordpress.org/plugins/subtitles/faq/" rel="ugc">Frequently Asked Questions</a>.
