Every installation of Divi adds a set of buttons to the WYSIWYG (TinyMCE) toolbar in the Classic Editor. These are dated, and most users who utilise the Divi Theme Builder or Page Builder will not use these.
This simple plugin removes the following Divi-specific icons from the toolbar:
<ul>
<li>Add ET Learn More Block</li>
<li>Add ET Box</li>
<li>Add ET Button</li>
<li>Add ET Tabs</li>
<li>Add Author Bio</li>
</ul>
This plugin is compatible with all versions of Divi that have the aforementioned buttons in the TinyMCE toolbar – this includes Divi 5.
