In a multiscreen App, how can I switch to another screen and close the current screen? It happens to me that it remains visible even if I take a close screen.
I found this @Anke extension very useful to close the application and leave no instance open when there are switchs between different screens »
And I found this 'Tribblehunter method' to make the switch between the screens, very functional *»

To get out of the application, once its final process is completed, it is not necessary to use the [Close Application] Block (from the control drawer)... Just invoke the extension and call by [Close Screen]

Which screen did you "take" and what remains visible?
