iMovie advanced tools option not present in preferences I'd like to enable Advanced Tools in iMovie preferences.

When I open preferences, I only see:



Using iMovie 10.0.9
I don't recall from which version, but at some point iMovie changed its interface so that all of the advanced tools were already built into the interface, so there's no need to enable it in iMovie's preferences. 

To see the various tools, just click on your clip and select the Adjust option to reveal the Advanced tools.
