PlugInstaller is a WordPress plugin-management plugin that eliminates the need to download a plugin archive, upload it to your FTP server and unpack it manually. With PlugInstaller, you can easily enter a plugin URL (e.g. directly from a plugin repository website like the WordPress.org plugin repository) within the admin interface which is in turn automatically downloaded and installed on your server or you can upload a file from your local file system which is also automatically installed. If you do no longer like one or more plugins that you previously installed, you can uninstall those plugins with a single click.
