How Do You Display the iTunes Downloads Window?

My Mac restarted a while ago, after I installed the latest OS X update. I have a number of apps set to launch at login, including iTunes. When I switched to iTunes, I saw the Downloads window.


Yet we know that Apple killed off that window in exchange for a not-always-visible ring at the right of the iTunes toolbar, which displays a popover when you click it.

Downloads popover

A correspondent mention recently, in an email, that he had seen this window, but couldn’t remember how he got it to display. This is the first time I’ve seen it in iTunes 12, and I’m wondering how it showed up. As I said, I did nothing but have iTunes launch at login.

Has anyone figured out how to get this window to display? I admit that I prefer this window to the popover.
