Provides a new dashboard widget to display all registered dashboard widgets and enables to remove the other dashboard widgets individually 
for all or selected roles (i.e. even from the screen options) in order to avoid irritation of your clients or other site contributors. 
When checked indiviually, widgets will be highlighted for identification of unknown widget names. 
The intention is to avoid confusion how to handle the screen options to not show or how to interpret unknown or uninteresting dashboard widget content. 
This plugin is self explanatory and can be accessed through the admin dashboard.
