Key features "One Click Plugin Updater":

· Single-click plugin upgrades in WP 2.3 and up. The techniques that this plugin uses are slightly different from the built-in plugin upgrade feature in WP 2.5, so it's possible that on some blogs the plugin updater works and the built-in updater doesn't (or vice versa).
· Upgrade all plugins with a single click (only in WP 2.5 and up).
· Visually identify plugins that have update notifications enabled. They get a yellow-gold marker in the "Plugin Management" tab.
· Quickly determine if there are any pending updates and how many plugins are active. This plugin displays that information right below the "Plugin Management" headline.
· Configure how often WordPress checks for plugin and core updates, which module is used to upgrade plugins (this plugin or the built-in updater), and other options. See Plugins -> Upgrade Settings.
· Easily install new plugins and themes (be sure to read the notes below). The plugin adds two new menus for this - Plugins -> Install a Plugin and Design -> Install a Theme.
· Delete plugins and themes from the Plugins/Themes tabs.
· Compatible with the OneClick Firefox Extension (up to version 2.1.2 of the plugin). Later versions use a new, improved FF addon : One-Click Installef for WP
· Global plugin update notifications.
· You can disable update notifications for inactive plugins.
· You can hide the little update count blurb displayed on the "Plugins" menu.
· Now with extra safety - uses the WordPress nonce mechanism for almost all tasks.

Requirements:

· WordPress 2.3 or higher
