https://www.youtube.com/watch?v=xkWE8nEdmcoat about 1:27, the purported fly-out menu for noise control (amongst others) does not appear by my moving the mouse to the edge of the screen. it did in the demo. now running Pro with Bottom and SI Mosaic. There does not appear a Gear icon in the SI window,either, as in other views.
