working session of the virtual hp-prime

[compsystems]

Hello, the working session of the virtual hp-prime, many times when the simulator is running is lost when the mobile device is shut down or the [back] button is pressed

Suggestions

1: the Android operating system button [back], made the simulator generate a dialog box that shows whether to close the session or not.

2: add to the simulator the option to save the current session, to avoid the loss of the work session

Thanks
