This is an addon for the Block Editor Customiser which allows you to hide core blocks in the Editor. 
Please be aware it is possible to make them visible again if the user has access to the ‘Show more tools and options’ 
menu where they can select the ‘Block Manager’ to reactivate the blocks hidden by this addon.
If you do not want this to happen the only way of preventing it is to hide the ‘Show more tools and options’ menu item which can 
be done from the main settings page in the Block Editor Customiser.
If you want to deactivate or uninstall this addon, then please uncheck all block types that have 
been checked, save the changes, and open a post or page before deactivation, otherwise any block types that have 
been previously hidden will remain hidden unless displayed using the ‘Block Manager’ mentioned above.
** NOTE: ** This plugin requires version 1.6+ of the Foxdell Folio Block Editor Customiser to work.

<h4>Remove “Proudly powered by WordPress”</h4>
This plugin removes the “Proudly powered by WordPress” for those who want to use the default theme for their website but don’t want everyone to know what they’ve used to build it. Content can then be added in its place with a new “Site Info” widget area on some themes.
For block themes, you do not need to use this plugin, just edit the footer template in the Site Editor. We do have a plugin, <a href="https://wordpress.org/plugins/template-editor/" title="Options for Block Themes" rel="ugc">Options for Block Themes</a>, that adds additional features and options to block themes.
This plugin works on all classic default WordPress themes (and child themes) including …
<ul>
<li>Twenty Twenty One (widget area not implemented as it’s not suitable)</li>
<li>Twenty Twenty (widget area not implemented as it’s not suitable)</li>
<li>Twenty Nineteen (widget area not implemented as it’s not suitable)</li>
<li>Twenty Seventeen</li>
<li>Twenty Sixteen</li>
<li>Twenty Fifteen</li>
<li>Twenty Fourteen</li>
<li>Twenty Thirteen</li>
<li>Twenty Twelve</li>
<li>Twenty Eleven</li>
<li>Twenty Ten</li>
</ul>
… and now includes the following additional themes (and child themes) …
<ul>
<li>Customizr (widget area not implemented when “Classical” theme style set)</li>
<li>Envo Shopper</li>
<li>GeneratePress</li>
<li>GreenLeaf</li>
<li>Masonic</li>
<li>MinimalistBlogger (widget area not implemented)</li>
<li>Neve (widget area not implemented)</li>
<li>NewsCard (widget area not implemented)</li>
<li>Newsup (widget area not implemented)</li>
<li>OnePress</li>
<li>Seedlet theme (widget area not implemented)</li>
<li>Solid Construction</li>
<li>Inspiro theme</li>
<li>Snaps (widget area not implemented)</li>
<li>Tonal</li>

</ul>
