@version        1.0.0
@description    Displays a "Delete" button per notification. This allows to delete a notification with just one click instead of opening the notification's context menu and click delete. (Side effect: this UserStyle hides/disables all other entries of the notification's context menu. To make them visible/usable again, you have to disable this UserStyle)
