JSN PowerAdmin leaves the standard admin menu items in place, but it does add some new (yet useful) links.
Quick "Uninstall" function
JSN PowerAdmin does not replace the existing Joomla admin area but works alongside it. Most notably, an "Uninstall" item has been added to components menu, enabling you to remove the component without having to navigate to the Extension Manager section and search for the extension.
Extended menu items
JSN PowerAdmin allows user to access quickly to the sub-items of each menu. For example, mousing over the Extension Manager opens up a submenu that gives you instant access to install, manage or update page.
