Here's a new extension worth a look, particularly if you manage more than one Joomla site. JAdmin! is a desktop tool that works with Windows or Linux. You can access any part of your Administrator with just one click. Although this saves a little bit of time, I couldn't really see the point of it at first, especially considering that this is a commercial extension. But if you are managing several sites, it would be extremely helpful to be able to jump straight into the desired area, without needing to remember a password. JAdmin! also displays the current user activity on all your sites.
