Frank - the developer of the plugin - pointed it out on a recent thread on Google+ where I was searching for a way to get rid of the available sidebar widgets.
Although it cannot get rid of the wpml widgets, it gets rid of everything else and that is only the tip of the iceberg. It does a lot, a lot more!
One suggestion would be to keep the position in the settings when saving as it becomes quite the scroll...
If you're looking for ways to customize the entire WordPress backend for yourself or for clients, then this is the plugin you want to install!
