All of this is window manager dependent.

There should be some visual queue indicating which window is
active. Maybe a checkbox or something.

The active window might not be top-most. It's up to the window
manager. In my fvwm configuration, I don't have windows pop to the
top when I'm working in them. I've have to explicitly click the
title bar to move them forward.
I don't think relying on window position in the stack makes
for a good user interface. I think you're better off with a
checkbox indicating which is current, and not changing it until
somebody clicks a different box. Just my opinion.
