Option to ask for confirmation prior to closing gnome-boxes on click of top right 'x' button
I use gnome boxes to run windows OS and often run it filling half of my host desktop. When I have an application maximized in guest I often accidentally click the close 'x' on gnome-boxes instead of the 'x' on the guest application that I really want to close.
I would proposal an option to enable a confirmation box popup when the gnome boxes 'x' is clicked. I understand that others may have a workflow that would be disturbed by this behaviour and suggest not changing the default behaviour, only allowing it as an option.
