BlogText (<a href="http://blogtext.mayastudios.com" rel="nofollow ugc">http://blogtext.mayastudios.com</a>) is a plugin for WordPress that allows you to use a simple wiki-like syntax (based on the Creole wiki syntax) to write your posts and pages. This syntax is easy-to-learn and fast-to-type. The goal behind BlogText is that you don’t need to write HTML anymore to achieve the desired text layout.
The following list lists some of the markups supported by BlogText. For a more complete list, see <a href="http://blogtext.mayastudios.com/syntax/" rel="nofollow ugc">BlogText’s syntax description page</a> (which is written entirely in BlogText syntax and demonstrates BlogText’s capabilities).
Supported markup:
<ul>
<li>Basic text formatting such as bold, italics, underlining, and strike-through</li>
<li>Lists</li>
<li>Tables</li>
<li>Internal and external links</li>
<li>Headings</li>
<li>Table of contents</li>
<li>Preformatted text and code blocks with syntax highlighting</li>
</ul>
BlogText also integrates itself into <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">WordPress’ classic editor</a> (which is the recommended way to write BlogText) by providing its own buttons (to create BlogText syntax), media browser integration, and help links. This make writing posts with BlogText even easier.

This plugin preserves the user-generated HTML markup in the TinyMCE editor. Unlike other plugins this one allows developers to work in the HTML tab AND end-users to work in the WYSIWYG Visual tab at the same time! No longer will your HTML markup be completely munged into an unrecognizable form when you switch between those tabs. And you don’t have to hang your users/editors out to dry when you hand off the project with a disabled Visual tab.
<h4>IMPORTANT: Please read the installation instructions carefully. If you have existing content it will not render properly after activating this plugin until you use the Fix It Tools.</h4>
(One user didn’t read or follow these steps and panicked thinking I ruined their website.)
It also supports HTML5 Block Anchor tags in addition to other HTML5 elements, something that is currently not supported in WordPress via any existing plugins.

Preserved HTML Editor Markup Plus

Preserves HTML and developer edits in HTML AND WYSIWYG tab.  Supports inline scripts/css, JavaScript code blocks and HTML5 content editing
