MRW Simplified Editor


Help your CMS editors create semantic content and style it with the theme for consistent formatting and portable content. This plugin removes blocks and other styling options to help editors focus.

Developers can adjust this plugin via filters. There are no settings.

I built this plugin for use on client sites. I hopes you’ll find it useful! This is an opinionated plugin. Read an in-depth reasoning behind the decisions made by this plugin in the post “A WordPress Formatting Manifesto.”

  • The Block Editor simplified, here with no colors or drop caps for the Paragraph block.

  • The "Classic" block of the WordPress 5.0 block editor reflects the impact of this plugin.

  • The Classic Editor/Block in all its minimal glory. This shows the default set of buttons and styles.

  • "Link Button" is an example of a text style that can be added with the mrw_mce_text_style filter. In this example, it's grayed-out by default since it can only be applied to links!

    unset( $disabled_style_variations['core/separator'] );

    return $disabled_style_variations;

It's easy to underestimate how much skill goes into formatting content to look nice in the WordPress editor. This plugin not only makes it easier for users to learn how to work with tinyMCE, but it also helps them get better results by removing buttons that really shouldn't be there in the first place. With this plugin, I don't have to spend my time explaining to every client why they should never use the color tool, the underline tool, or heading 1. Plus, no one will ever get confused because the second row of buttons is hidden, and they don't know where it went. Developers can configure this plugin as they need to, everyone else can just activate it and let it do its thing. It's a great plugin.

The title of the plugin might be a mouthful, but it does exactly what i wanted. Simplifies the tinymce editor to a single line of the most useful options and removes everything thats not. This is something you could do on your own, but in situations where you don't want to maintain your own code, this plugin is darn simple and useful.
