It’s a minor thing in the UI but it seems to be inviting disaster. The keyboard shortcut window in both programs (on Mac at least) look almost identical, which is great for ease of use and efficiency and quick muscle memory. However there is one button at the bottom right of each window in almost exactly the same place that in the Layout version innocently closes the window, and in the SketchUp version immediately erases all your shortcuts without further warning. Maybe the SketchUp nuclear option button could look a little more different? In a different place perhaps to avoid a muscle memory accident?
