Live preview in the customizer allows you to see what plugins do to your site instantly. This experimental plugin brings the ability to activate and deactivate plugins from within the customizer. Plugin installation and updates could be a potential future phase depending on the success of this experiment.
Unfortunately, the customizer preview cannot currently reflect changes to the active plugins list. Additionally, plugins are not sandboxed – broken plugins activated from here could break your site. Use this plugin with caution. However, changes are not published to your live site until you “Save and Publish,” and the plugin manager does functionally activate and deactivate plugins. Preview functionality requires hooking into WordPress before plugins are loaded (for obvious reasons), which isn’t possible to do within a plugin.
See https://core.trac.wordpress.org/ticket/40451 for additional discussion.

<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>
