<h4>Block Editor Features</h4>
This plugin greatly simplifies the block editor by hiding a significant number of blocks, block settings, and other editor-facing features.
The plugin is regularly updated following major WordPress version updates. Filters are provided for developers to adjust what is hidden (including making it easier to hide additional blocks).
<ul>
<li>Infrequently Used Core Blocks such as Verse, Table, Audio, Video, etc., and all Query- and Site-related blocks when using the Post editor. See FAQ for <a href="https://wordpress.org/plugins/mrw-web-design-simple-tinymce/#faq" rel="ugc">full list of hidden blocks</a>.</li>
<li>All Core Block Styles and the “Default style” feature</li>
<li>Some Block Editor Settings: Drop Cap, Text-indent, Heading 1, Heading 5, Heading 6, font sizing by pixel, open links in new tabs (mostly hidden), duotone, text styles like line-height and letter spacing, inline formats including Highlight and Inline Image, etc.</li>
<li>Default color, gradient, and duotone settings (Custom theme palettes/settings are never hidden)</li>
<li>Core Block Patterns (WP 5.5+)</li>
<li>Block Directory (WP 5.5+)</li>
<li>Infrequently Used Jetpack Blocks – See <a href="https://wordpress.org/plugins/mrw-web-design-simple-tinymce/#faq" rel="ugc">FAQ for full list of hidden blocks</a>.</li>
<li>“Upload” and “Insert from URL” image options to encourage use of Media Library</li>
</ul>
The plugin also improves the editor by:
<ul>
<li>Increasing prominence of contrast errors</li>
<li>Styling “Save draft” as a button</li>
</ul>
<h4>Classic Editor / Classic Block Features</h4>
Reduces editor to a single row of buttons: “Styleselect” (Headings 2-4 and Blockquote as well as Strikethrough, Subscript, Superscript, Preformatted, and Code), Bold, Italic, Add/Edit Link, Break Link, Horizontal Rule, Paste as Plain Text, Remove Styles, Special Characters, Undo, Redo, Help, Distraction Free Mode.
<h4>Note on WordPress version Support</h4>
