Currently, when user navigates to WooCommerce > Orders and clicks on Order Notes icon, it opens the order itself.
WooCommerce Order Notes Window plugin overrides this behaviour by opening modal window with
the content of the Order Notes meta box.
Additionally, information about order note author is stored and displayed.
WooCommerce 2.0.x is required. The plugin is not compatible with WooCommerce 2.1 or newer.
