New Feature: "Show in preview"

[SkrOYC]

A new feature was added to the editor where you can manually select which view you want to see on the emulator.

I didn't found any announcement about it @lizlynch

Thank you for calling this out! It was definitely an oversight. 
I have added a section in the documentation:

I will update the release notes for June 2nd to mention of it. 
Thanks again, Liz
