Product Rating Widget
The product rating widget allows administrators to provide feedback on their Plesk user experience. A form which gives the opportunity to rate the product and send comments appears after one month of using Plesk. If the administrator chooses to provide feedback later, Plesk adds the Provide Feedback button to the Navigation Pane of the Server Administration Panel and to the bottom of the Customer Panel in Power User view.
You can hide the product rating widget so that customers and resellers do not see it.
