Vizio CoStar v5.3.

Currently, in order to close all 'open' applications I must:

1. Press the big square 'V' button on the CoStar remote to open the running (?) app list
2. Press up to select 'X'
3. Press 'OK' to close the application
4. Press the big square 'V' button on the CoStar remote to close the running (?) app list
5. Return to #1

It would be great if I could close all applications at once. And/or just show the 'X' application close button for all applications.

I recognize that this is an ARM device.
