double modal dialog madness - android studio component installer in IntelliJ

I wanted to write a quick test but I was 'missing system image'. I clicked on it and whoa, I am in the middle of a long download with no 'Background' button only "Cancel". IntelliJ is unusable and I must wait. I'm at home where the internet connection is slow.

Any download windows should have a "Background" button and definitely should not lock up the IDE. I guess I'll go get some snacks and take a nap.

Also, even though the SDK Quickfix Installation window is movable, it cannot be minimized. The windows below, Select Deployment Target and the main window are not even movable or minimizeable.
