IMPORTANT! Version 0.2.1 fixes a severe bug that could lead to complete unusability of your wordpress plugins when installing a corrupt plugin package. UPGRADE IMMEDIATELY!
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.
To stay informed about plugin updates, there is an automatic update checking mechanism built into your plugins management page. This plugin completely replaces the standard plugins management
page to incorporate all functions from PlugInstaller into a redesigned and more usable plugin management page.
With PlugInstaller you will no longer have to use any other software than your WordPress administration interface to install or uninstall plugins. In addition to that, plugin installation will hardly last more than 5 to 10 seconds with PlugInstaller, as there is no user interference required. You can also display the readme file provided along with any installed plugins with a single click from your plugin management page.
As of version 0.2, you will also be able to install critical plugin packages that do not contain the proper directory names inside the zip package.
