Any way to hide or minimize the Debug Test Mode window in Twine 2?

When running a passage in Test Mode in Twine 2 (Mac OS - Harlowe Story Format), is there a way to hide or minimize the window in the bottom right corner of the passage? The window shows the running list of variables and the "Debug Mode" button.

It is very useful, but when I try to test the window size as a half-desktop-screen (approx the screen size of an iPad in portrait mode) it covers text in the passage. It's not there when I "play", but I don't want to play through the whole game to get to this one page to test it.

Any ideas?

Thanks!
