An ultralight plugin to customize the admin <a href="https://wordpress.org/support/article/toolbar/" title="WordPress support article on Toolbar" rel="ugc">Toolbar</a> and add a shortcut to the plugins page.
Ever felt the need to navigate to the Plugins page directly from the site front-end? Well. This plugin does just that. Nothing more. Nothing less. Saves the hassle of going to the dashboard and then navigating to the Plugins page.
In the site front-end, a link will be added to the admin toolbar that takes you to the Plugins page in the site back-end. Note that this feature will be available only for the users who can install/activate/update plugins.
This functionality is particularly useful during the development of the website.
