Hello! 
I guess this is more of a feature request than a question: When I complete a project, I typically change the Window Background to white in the Lesson Settings.  This gives a nice, clean look in our LMS. However, when I need to go back in to make updates or changes, It's impossible to see the stage area without resetting the Window Background to something else and then back again. Is it possible to add a frame around the stage when editing but use the Window Color only in the published version of the project? 
Thanks! 
Scott

Hi Scott,
That's a great idea!  We'll add it to our enhancement list.

In the meantime, you can add a shape to one of your Masters, and turn off the Start Visible property, so it will show up while authoring, but never at runtime.  See attached image.  It's the same size as my stage, it has a Fill of "none", and thick dark line, so I can see it on other pages.  Doesn't really matter if it's above or below the page level content (since the Fill is set to None).  You can also Lock it in the Cast, so you don't accidentally click on it.

Hope that helps!
