Thanks for the alternate suggestion. This actually helped a lot when coming up with the solution to your other request. Previewing a single module was going to require a ton of new code updates to do it properly. , so I decided to work on this instead. After I got this working I added on the play to the end of it and I think it does what you originally wanted.
If you watch the screen you'll see the other modules turn off before the preview launches. They all turn back on while you are playing it.
