Please add ApplicationCover

Feedback from one of my Enterprise Customers after presentation of new Qt Quick Controls 2:

They have a Security Policy requiring not to show sensible data from minimized apps. This is a must-have and they demonstrated to me that even Angular and Ionic can do this.

As default Qt shows last visible content minimized.
There should be a way to design an Application Cover which automatically will be used if App is minimized and hides real data.

This should be available for Android, iOS and Windows 10.

I'll try to find a workaround with Qt.application.state but would be great to have something like:

ApplicationWindow {
// ...
header: ...
footer: ...
cover:
