I agree it would be great if the download manager was a public API, but
I've been given the feeling that's unlikely to change any time soon :(.
I would say that "re-use the window that I created earlier, if you still
have it" would make the most sense because the user may have used the
browser to get to another webpage between usage sessions of the
AndAppStore client so the "keep the window that's currently on top"
approach would end up with two apk download windows in the browser
instead of one apk download window and a window holding the page the
user navigated to.
